A circle has a radius of 16 cm Find the length s of the arc

A circle has a radius of 16 cm. Find the length s of the arc intercepted by a central angle of 165 degree. Do not round any intermediate computations, and round your answer to the nearest tenth.

Solution

Length of arc, s= radius , r * theta

theta=165 degree=165 pi/180=11pi/12radian

s= 16* 11pi/12=46.1 cm
