The circumference of a circle with a 20.5 inch diameter is 64.4 inches.
If the diameter of a circle is 12 inches the circumference is: 37.7 inches (diameter x Pi = circumference).
I assume you want the circumference which is pi times the diameter, so for 37 inch diameter the circumference would be about 116.24 inches.
The circumference of every circle is (pi) x (diameter).The circumference of this particular circle is 30 pi.
Divide the circumference of a circle by pi to obtain the diameter. Diameter of a 36 inch diameter circle is 36/3.1416 inches , or 11.459 inches.
The diameter of a circle that has a circumference of 125 centimeters is: 39.79 cm (circumference divided by Pi = diameter).
The circumference of a 6 inch diameter circle is: 18.8 inches. (diameter x Pi = circumference)
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 4-inch diameter circle is: about 12.57 inches. (diameter x pi = circumference).
circumference = pi*diameter so diameter = circumference/pi = 4.456 inches
31.4 in
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
The circumference is equal to the diameter multiplied by pi. Therefore, if you know the circumference, you can divide by pi to get the diameter.
