For a circle of radius 8 feet, find the arc length s subtended by a central angle of 10 degrees.

Given:

radius 8 feet

Solve for the circumference,

C = 2 π r

C = 2 * 3.14 * 8ft

C = 50.24 ft

A circle has 360°, we need to divide it by 10 degrees to compute for the arc length.

360° / 10° = 36

50.24 ft / 36 = 1.395 or 1.40 ft
