Find the missing quantity. Let 0 represent the central angle of a circle, r represent the radius of the circle, and A represent the area of the sector of the circle. r = 8 in., 0= 5 rad, A=? A = in.2 (Simplify your answer. Type an integer or a decimal.)Find the missing quantity. Let 0 represent the central angle of a circle, r represent the radius of the circle, and s represent the length of the intercepted arc. r = 4 m, 0 = 40 , s=? S= m (Type an integer or decimal rounded to the nearest thousandth as needed.)Find the missing quantity. Let 0 represent the central angle of a circle, r represent the radius of the circle, and A represent the area of the sector of the circle. r = 5 in., 0 = 4 rad, A=? A = in. (Simplify your answer. Type an integer or a decimal.)Find the radian measure of an angle at the center of a circle with radius 60.0 cm that intercepts an arc length of 113 cm. The measure of the angle is (Round to two decimal places as needed.)Find the length of the arc, s, intercepted by the given central angle, 0, in a circle of radius, r. 0 = 40 rad; r =5 cm SE cm
