Answer 1

Question:

A stationary horse on a carousel makes 11 complete revolutions. Through what radian measure does the horse revolve?

Solution:

There are 2π radians in a revolution. (One revolution is the distance of the circumference, which is 2π radius-lengths).

Then, 11 revolutions is 11 x 2π radians = 22 radians.

Then, the correct answer is 22 radians.
