C = pi times diameter. This is 3.14 times 21, which equals 65.94.
Circumference = 24*pi = 75.398 inches to 3 dp
circumference = 2 * pi * r ----> pi is a constant in this case circumference = 2 * 3.142 * 10 ------> radius is 1/2 of a diameter So, circumference of this circle is 62.84 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
The equation for circumference is Pi(diameter), so the exact value of the circumference of a tire with a 29 inch diameter is 29pi.
The circumference of a circle with a diameter of 20 feet is: 62.83 feet (diameter x Pi = circumference).
