- 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.

Circles Circles - central angles. A central angle of a circle is an angle where its vertex is the center of the circle and its sides are radius of the circle. In order to measure an arc of a circle we use the size of the central angle that forms the arc.

What is Ï6radians in degrees? #pi/6# radians is 30 degrees. A radian is the angle subtended such that the arc formed is the same length as the radius. There are #2pi# radians in a circle, or 360 degrees. Therefore, #pi# is equal to 180 degrees. #180/6=30#.

Circle of latitude The latitude of the circle is approximately the angle between the equator and the circle, with the angle's vertex at the Earth's centre.The equator is at 0°, and the North and South Pole are at 90° north and 90° south respectively.nlike circles of longitude, which all are great circles with the centre of Earth in the middle, the circles of latitude get smaller as the distance from the Equator increases. Their length can be calculated by a common sine or cosine function.

Degree (angle) One degree (shown in red) and. eighty nine degrees (shown in blue) A degree (in full, a degree of arc, arc degree, or arcdegree), usually denoted by ° (the degree symbol), is a measurement of plane angle, defined by representing a full rotation as 360 degrees. It is not an SI unit, as the SI unit for angles is radian, but it is mentioned in the SI brochure as an accepted unit. Because a full rotation equals 2π radians, one degree is equivalent to π180 radians.

About Lenses Converting radians to degrees: To convert radians to degrees, we make use of the fact that p radians equals one half circle, or 180. This means that if we divide radians by p, the answer is the number of half circles. Multiplying this by 180 will tell us the answer in degrees. So, to convert radians to degrees, multiply by 180/p, like this:

- The measure of an arc is given in degrees. The length of an arc depends on the size of the circle and is measured in standard units, such as inches, centimeters, etc. The circumference of a circle is an arc measuring 360o.rcs are measured in degrees. This is not the same as the length of an arc, which depends on the size of the circle. The measure of a minor arc is defined as the measure of its central angle: The measure of a major arc is 360o minus the measure of the corresponding minor arc:

- Converting degrees to radians: To convert degrees to radians, first find the number of half circles in the answer by dividing by 180. But each half circle equals p radians, so multiply the number of half circles by p. So, to convert degrees to radians, multiply by p/180, like this:

Trigonometry/Radians Let us take one millionth of a circle. In degrees that is 0.00036 degrees. In Radians that is Radians. The angle of course is the same. It's one millionth of a circle, however we choose to measure it. It is just as with weights where a weight is the same whether we measure it in kilogrammes or pounds.he Radian Measure [edit]. There are Radians in a complete circle. It is traditional to measure angles in degrees; there are 360 degrees in a full revolution. In mathematically more advanced work we use a different unit, the radian.

Convert radians to degrees, in pi terms ? you know that when r is the radius the circumference will be 2pi x r or that it takes 6,28 radius to make the circumference. A radian is the part of the circle that 1 radius would cover. or about 57,3 degrees.

- The radius of the circle is equal to the hypotenuse OP, and has length 1, so we have sin θ = y /1 and cos θ = x /1. The unit circle can be thought of as a way of looking at an infinite number of triangles by varying the lengths of their legs but keeping the lengths of their hypotenuses equal to 1.

The circumference of a circle is 34 cm. Find the diameter, the radius, and the length of an arc of 70Â°.? So: Diameter = Circ/Pi The radius is 1/2 of the diameter. The length of the arc of 70 degrees? Well, there are 360 degrees in a circle, therefore: 70/360 = Length of Arc/Circumference Based on that, I can't see any of the optios being correct.In fact, simple logic says that none of your answers can be correct. You say the circumference is 34cm.he length of the arc of 70 degrees?

- How to Convert Degrees to Radians. Degrees and radians are two units for measuring angles. A circle contains 360 degrees, which is the equivalent of 2π radians. This means that 360° and 2π radians, represent the numerical values for going once around a circle. This means that 180°, or 1π radian, represent going halfway around a circle.

- A unit for measuring angles. 180° = π radians, and 360° = 2π radians. The number of radians in an angle equals the number of radii it takes to measure a circular arc described by that angle. Note: 360° equals 2π radians because a complete circular arc has length equal to 2π times the radius. Formula: θ = s/r. θ = measure of the central angle in radians.

- The Circumference of a Circle is defined by the formula: C = 2πr. where r is the radius of a circle. The diameter of a circle is twice its radius or 2r. and therefore C = πd (where d is the diameter). So since d = 5 feet, the Circumference of the circle is 5π feet. Approximating π = 3.14159. We get C = 15.7079 feet.

Angles â The Revolution In elementary school, we learn that angles are measured in degrees (°). 1 full circle = 360°. Historical note: The number 360 comes down to us from antiquity. 360 was useful to ancient astronomers because it is approximately the number of days in the year.

- All the way around the circle is 360o and the 50% wedge goes half way around so the central angle for the 50% wedge is 50% of 360o which is 1/2 × 360o = 180o. The 40% wedge uses 40% of 360o as its central angle and hence the angle is 40% of 360o or 40/100 × 360 = 144o.

Degree (angle) One complete turn (360°) is equal to 2π radians, so 180° is equal to π radians, or equivalently, the degree is a mathematical constant: 1° = ⁄180. The turn (or revolution, full circle, full rotation, cycle) is used in technology and science. 1 turn = 360°.
