circumference=2(pi)r
so divide the given circumference on 2pi, it will give radius. Now multiply radius by 2 you will get the diameter.
Divide 8.25 by pi to find the diameter of the circle
circumference = pi x diameter where pi = 3.14 circumference = 3.14 x 27 = 84.78 inches
The circumference of a six-inch diameter circle is: 18.8 inches.
The circumference of 9 inch diameter circle is about 28.27 inches.
The circumference of a circle with a 20.5 inch diameter is 64.4 inches.
The circumference of a circle with a 39 inch diameter is 122.52 inches.
The circumference of a 6 inch diameter circle is: 18.8 inches. (diameter x Pi = circumference)
The circumference of a 4-inch diameter circle is: about 12.57 inches. (diameter x pi = circumference).
circumference = pi*diameter so diameter = circumference/pi = 4.456 inches
pi*diameter = 38 Divide both sides by pi to find the diameter: diameter = 12.09577567 or 12 inches to the nearest inch.

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