Find the radian measure of the central angle of a circle of radius r=100 inches that intercepts an arc of length s=70 inches

Question

This is a question about radian and and the inches intercepts an 

Answer 1

s = θ·r

• s = arc length = 70 in.
• θ = central angle in radians
• r = radius = 100 in.

 

s = θ·r

70 = θ·100

 

Solve for θ.
