Find central angle given area and radius

WebSix of the sectors have a central angle measure of one radian and an arc length equal to length of the radius of a circle. The seventh sector is a smaller sector. The seven … WebOne radian is the angle measure that we turn to travel one radius length around the circumference of a circle. So radians are the constant of proportionality between an arc length and the radius length. It takes 2\pi 2π radians (a little more than 6 6 radians) to make a complete turn about the center of a circle.

WebExample: find the area of a sector. As established, the only two measurements needed to calculate the area of a sector are its angle and radius. For example, if the angle is 45° and the radius 10 inches, the area is (45 / 360) x 3.14159 x 10 2 = 0.125 x 3.14159 x 100 = 39.27 square inches. WebDetermine the radius, the length of the curve, and the distance from the circle to the chord M. Solution to Example 7.5 Rearranging Equation 7.8,with D = 7 degrees, the curve’s radius R can be computed. Equation 7.9 allows calculation of the curve’s length L, once the curve’s central angle is converted from 63o15’34” to 63.2594 degrees.
