- How to find the area of a square: The area of a square can be found by multiplying the base times itself. This is similar to the area of a rectangle but the base is the same length as the height. If a square has a base of length 6 inches its area is 6*6=36 square inches.

- Surface Area = Areas of top and bottom +Area of the side. Surface Area = 2(Area of top) + (perimeter of top)* height. Surface Area = 2(pi r 2) + (2 pi r)* h. In words, the easiest way is to think of a can. The surface area is the areas of all the parts needed to cover the can.That's the top, the bottom, and the paper label that wraps around the middle. You can find the area of the top (or the bottom). That's the formula for area of a circle (pi r2).Since there is both a top and a bottom, that gets multiplied by two.urface Area = Areas of top and bottom +Area of the side. Surface Area = 2(Area of top) + (perimeter of top)* height. Surface Area = 2(pi r 2) + (2 pi r)* h. In words, the easiest way is to think of a can. The surface area is the areas of all the parts needed to cover the can.

Areas and Volumes - A Lesson in Proportionality and the Value of Ratios Consider a square that is some distance D on a side - the area is D x D= D2 (with the appropriate units - meters2 or km2 or feet2 (if you cannot handle metric)) Now, double the size of the square so that each side is 2D - the area is then 2D x 2D = (2D)2 = 4 x D2 (with same appropriate units).

Seventh grade math - Circles: calculate area, circumference, radius, and diameter Amanda, The area of a circle is given by the formula A = π r 2, where A is the area and r is the radius. The circumference of a circle is C = 2 π r. If we solve for r in the second equation, we have r = C / (2 π).Now we use this to replace r in the first equation: A = π [ C / (2 π) ] 2.manda, The area of a circle is given by the formula A = π r 2, where A is the area and r is the radius. The circumference of a circle is C = 2 π r. If we solve for r in the second equation, we have r = C / (2 π).

Area of a Circle The area of a circle is the number of square units inside that circle. If each square in the circle to the left has an area of 1 cm 2, you could count the total number of squares to get the area of this circle.iven the radius or diameter of a circle, we can find its area. We can also find the radius (and diameter) of a circle given its area. The formulas for the diameter and area of a circle are listed below:

- The base of the triangle is equal to a side of the square, which is 8 cm. You can use these numbers to determine the area. A of square = s ^2 = 8^ = 64 cm^2. A of triangle = (1/2) * b * h = (1/2)* 8 * 2 = 8 cm^2. Then you just add the areas together to get the total area of the figure. A = 64 + 8 = 72 cm^2.

- To find the area, you need to divide the shape into a rectangle and a triangle: The area of the rectangle is 5 × 4 = 20cm 2. The base of the triangle is calculated by subtracting the base of the rectangle (4cm) from the total length of the shape (10cm).

- Plug the appropriate values into the formula for finding the area of a triangle. The formula for finding the area of a triangle is called Heron's formula and is the following: Area = √{s (s - a)(s - b)(s - c)}. Remember from the previous step that s is the semi-perimeter and a, b, and c are the triangle’s three sides.

Scalene Triangle Area of a Scalene Triangle Formula. Area of a Scalene Triangle can be calculated by using the following formulas, Area = $\frac{1}{2}$ * b * h. where, b is the base and h is height of a scalene triangle. or Area = $\sqrt{s(s - a)(s - b)(s - c)}$ (when all sides are given) where, s = $\frac{a + b + c}{2}$ is the semi-perimeter of the triangle.

- If someone gives us a square that has an area of 25 square cm, it is pretty easy to guess and check and figure out that the sides of the square are 5 cm. However, when the area of a square is 23 square cm, guessing and checking does not seem to lead to an exact answer—we need to find the square root. The radical and the radicand make up the notation used for square roots.

- 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.

How to Calculate the Volume of a Cone Ad. 2. Use the radius to find the area of the base circle. To find the area of the base circle, you can just use the same formula you'd use to find the area of a circle: A = πr2. Plug .5 in for r to get A = π(.5)2 and square the radius and multiply it by the value of π to find the area of the circular base. π(.5) 2 = .79 in. 2.
