Question

The angular velocity of a point on a circle with radius of 12 feet is 15pi radians per second. Find the speed of the point on the circle.

Answer 1

i think you can use L = rc where L is length along the circle, r = radius and c is the angle in radians.

Answer 2

r = 12 , c = 15pi
the answer will be in feet per second

Answer 3

simply multiply

Answer 4

L is the length the point will travel in 1 second This will give you the speed per second.
