In Exercises 71-74, find the length of the arc on a circle of radius r intercepted by a central angle 6. Express arc length in terms of TT Then round your answer to two decimal places. Radius, r Central Angle, 0 71. 12 inches 8 45o 72. 16 inches 60° 2250 73. 8 feet 74. 9 yards 315°

Solution

arc S = radius X angle , where angle is in radian.

So first we need to change the angle into radian for that we eed to multiply with pi/180 in angle.

So theta = pi/3

And arc S = 16* pi/3 .
