Circumference = pi*d = 69 inches
The circumference of a circle with a 20.5 inch diameter is 64.4 inches.
Circumference=2.5 inches
The circumference fof a circle with a 10.5 inch diameter is pi*10.5 = 33.0 inches, approx.
If the diameter of a circle is 12 inches the circumference is: 37.7 inches (diameter x Pi = circumference).
circumference = pi*1.205
What is a "8 inch ball" ? Is 8 inches the diameter ? Then its diameter is 8 inches. Is 8 inches the radius ? Then its diameter is 16 inches. Is 8 inches the circumference ? Then its diameter is about 2.546 inches (rounded).

The equation for circumference is Pi(diameter), so the exact value of the circumference of a tire with a 29 inch diameter is 29pi.
circumference = pi * diameter so, diameter = 9/ pi = 2.86
