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

So the radius of the circle (merry-go-round) is 5
Therefore, the circumference is 2π(5)=10π
If we want to find 1 second, out of six seconds, that means we divide the circumference by 6. 10π/6=
`\p (5)/(3) \pi`≈5.235 feet per second
