26 A circle has a radius of 7 ft . Find the radian measure of the central angle θ that intercepts an arc of length 10 ft .

Question

Do not round any intermediate computations, and round your answer to the nearest tenth.

Answer 1

Arc length is:

 

s = θr

• s = arc length = 10 feet
• θ = central angler in radians
• r = radius = 7 feet

 

s = θr

10 = θ·7

 

Solve for θ.  Units are radians.
