Question

If the unicorn seat on a merry–go–round is 5 feet from the center, and the merry–go–round completes a full rotation in 6 seconds, how many feet does the unicorn travel in one second?

Answer 1

Find the diameter first which is 10. Than multiply it by pi to find the circumference.
So the circumference = 10pi and that takes 6 seconds to travel. So you just divide 10pi by 6 giving you 10pi/6 or 5pi/3.
