Trevor needs a new bicycle tire. His tire has a circumference of about 113.04 inches. What is the diameter of his tire?

The formula for circumference is 2 (pi) r, so first you would divide by 2, which is 56.52 (about) then divide by pi and you get 18. So the radius is 18, so multiply 18 by 2 and you get 36.

So therefore, the diameter is 36 inches
