What is pi, and how did it originate? If you could measure and divide perfectly, you would get 3.141592653589793238..., or pi. Otherwise said, if you cut several pieces of string equal in length to the diameter, you will need a little more than three of them to cover the circumference of the circle. Pi is most commonly used in certain computations regarding circles. Pi not only relates circumference and diameter. Amazingly, it also connects the diameter or radius of a circle with the area of that circle by the formula: the area is equal to pi times the radius squared.

How to Calculate the Arc Length, Central Angle, and Circumference of a Circle Calculating Arc Length. Calculate the circle's circumference. Calculate the central angle of your circle, using the protractor, then represent this angle as a fraction. As there are 360 degrees in all circles, make 360 the denominator of the fraction. The angle measurement is the numerator. Divide the numerator by the denominator to place the number in decimal form. Multiply the circumference by the decimal to learn the arc length of that section of the circle.

How To Use a Compass with a USGS Topographic Map Read your map bearing from the compass dial. Make sure the bearing agrees with your direction of travel – for example, if you intend to travel due east, the bearing is 90 degrees, not 270 degrees. E). : If the local declination is positive, then subtract the declination amount from the bearing you just derived.) Place the compass on the map so the baseplate is parallel to the line you drew. Make sure the direction of travel arrow points to your destination. E) Rotate the dial until compass ring north agrees with map north. Do not move the compass when you rotate the dial.

Using straight edge and compass, divide given circle into 9 parts of equal area? Draw a line from the center of the circle to any point on the circle. Adjust your compass to an angle of 40 degrees. (360/9=40) Place the point of the compass on the point where the initial line intersects the circle, and inscribe an arc that intersects the circle.est Answer: Draw a perpendicular pair of diameters in the circle, and divide them into thirds. Then draw in 5 circles of diameters 1/3 of the original diameter. Each of the circles have 1/9th the area of the original, leaving 4 equal odd shaped pieces.

HOW TO DIVIDE A SQUARE INTO FOUR (4) EQUAL PARTS 8:45:00 PM Math Realm 6 comments. There are different ways of doing this. I'll show some of the solutions then you'll find the rest. Solution 1: The easiest way to divide the square into 4 equal parts is to draw three vertical lines or three horizontal lines forming four (4) equal areas.This can be shown in the figure below, where each part is shaded with a different color.olution 4: You can also cut the square by a horizontal line or a vertical line, then cut each half into two equal triangles. There are still other ways of dividing a square into 4 equal parts. Find them and share them here... comment below.

True Position If you only have the diameter of a circle, convert it to the radius. Do not try to find area until you convert the diameter to the radius. A radius is half the length of the diameter. Divide the diameter by 2 to get the radius, for example: A circle with a diameter of 10 would have a radius of 5.A circle with a diameter of 1,050 would have a radius of 525. radius is half the length of the diameter. Divide the diameter by 2 to get the radius, for example: A circle with a diameter of 10 would have a radius of 5.

How To Use a Compass with a USGS Topographic Map A compass with adjustable declination allows you to rotate the orienting arrow independently of the compass dial. If you have such a compass, you may calculate your map bearing without adding or subtracting the amount of local magnetic declination.) Place the compass on the map so the baseplate is parallel to the line you drew. Make sure the direction of travel arrow points to your destination. E) Rotate the dial until compass ring north agrees with map north. Do not move the compass when you rotate the dial.

- We only had one previous step in this example so the distance measured is 12 plus 7.75=19.75 miles. If we had stepped the dividers two times before adjusting for the final measurement, the distance measured would have been 12 plus 12 plus 7.75 or 31.75 miles.o measure, set the dividers to a whole number, in this case we use 12, and walk the dividers along the line. The distance between the buoys is 24 nautical miles (two steps of 12 miles each).

How do you control eyelashes that grow in the wrong directions, when lower lashes are 1/2 curly, 1/2 straight? show more My lower lashes are a problem. If they were shorter and lighter, it wouldn't be so obvious but they are long and dark so it's hard not to notice how messy they look. I can't seem to get them to go the right way...I don't know if they just grow in crooked or if they somehow curl that way.

THE GLOSSARY OF 1 While 6 contains no perfect squares, 18 equals 9 * 2. 9 is a perfect square, so rewrite the square root of 18 as the square root of 9 times the square root of 2. 2  Rewrite the entire expression. 3  The expression becomes the square root of 9 times the square root of 2 times the square root of 6.ultiply the radicands. For instance, the square root of 5 times the square root of 15 equals the square root of 75 because 5 * 15 = 75. 4. Simplify the radicands to remove any factors that are perfect squares.

- For example, suppose you want to find the area of a circle with a diameter of 18 centimeters. You have the radius of 9, so substitute it into the formula, as follows: A = pi(r^2) , so A = (3.14)(9^2) . Remember that squaring a number means multiplying it times itself, so 9 squared is 9 times 9. radius is half the length of the diameter. Divide the diameter by 2 to get the radius, for example: A circle with a diameter of 10 would have a radius of 5. A circle with a diameter of 1,050 would have a radius of 525.

Pi Since the ratio of the circumference to the diameter in every circle equals pi, it is easy to determine the formula for finding circumference, C = . Students should remember from Chapter 7 that a diameter is twice the measure of a radius, so the formula C = 2 can also be used.

- There are few other numbers as small as 360 that have so many different factors. This makes the degree a very nice unit to divide the circle into an equal number of parts. 120 degrees is 1/3 of a circle, 90 degrees is 1/4, and so on. So while a deeg, being 1/100th of a circle, may seem nice and round to us ten-fingered folks, it isn't so convenient for dividing a pie into thirds.

- Draw a line through the points at which these new circles intersect. This straight, horizontal line should cut through the overlap space of the two new circles. This line is the second diameter of your original circle, and it should be exactly perpendicular to the first diameter line. 7. Find the center.

- Circle: 2 x (pi) x r. To find the perimeter of a circle, you need to know the length of the radius (r) or the length of the diameter (d) (the diameter is the same as 2 x r in the formula). The radius of a circle is the distance between the center and the outside edge.Pi is approximately equal to 3.14.f you already know the length and the width of the rectangle, use this formula to find the perimeter. Parallelogram: Perimeter = (2 x a) + (2 x b). Like rectangles, parallelograms have two sets of parallel sides that are the same.

- Locate the center-point (vertex) of the angle. 3. Place the tip of the compass on the vertex of the angle and draw an arc which cuts each arm of the angle at two different points. Use whatever width of the compass you want to. Let us call this arc as the first arc. 4. Place the tip of the compass on one of the points where the first arc cuts an arm of the angle. Draw a second arc somewhere in the region contained between the arms of the angle. Use whatever width of the compass you want to.
