Question

A circular ring has a diameter of 20 meters, find its circumference

Answer 1

I think the answer is a. 62.8

Answer 2

You must know that the formula for getting the circumferance is circumferance=pi times diameter, so in your problem it would be 62.8 = 3.14x (x is the variable standing for the diameter) so then you divide 62.8 by 3.14 either with long division or by using a calculator and you get 20

The answer to your question is A. 62.8 meters.

Hope that this helps, have a great day, chao!!
