A circle has a radius of 13 inches. Find the length of the arc intercepted by a central angle of 1.7 radians.?

Answer 1

A circle has a radius of 13 inches. 

The length of the arc intercepted by 

a central angle of 1.7 radians is 22.1 inches.

Answer 2

The formula for arc length is really simple when working with angles in radians.

s = rϴ

(arc length) = (radius) * (central angle)

= 13 * 1.7

= 22.1 inches

Answer 3

circumference = 2π13 = 26π

arc = 26π(1.7/2π) = 13•1.7
