Question

A child rolls a ball 3.5m to another child. If the ball makes 15 revolutions what is its diameter?

Answer 1

if the ball completes 15 revolutions, then the same point on its circumference has been passed 15 times. If it takes 3.5m to do this, 15x the circumference must equal 3.5m.

Find the circumference, then find the diameter

Answer 2

Oh, That's a much nicer way of putting it. I never would've thought of it like that, brain just doesn't work that way lol. Thanks.

Answer 3
