3.5 inches
21"/6" =3.5"
The equation for circumference is Pi(diameter), so the exact value of the circumference of a tire with a 29 inch diameter is 29pi.
You divide the circumference by pi or 3.14.

The circumference of a circle can be calculated using the formula C = πd, where C is the circumference, π is approximately 3.14159, and d is the diameter of the circle. Given a diameter of 2.5 inches, you would plug this value into the formula: C = π(2.5) = 7.85398 inches. Therefore, the circumference of a circle with a diameter of 2.5 inches is approximately 7.85 inches.
Circumference = Pi X Diameter; Pi (3.141590) x 66 = 207.3 In.
C = pi times diameter. This is 3.14 times 21, which equals 65.94.
The circumference of a circle that has a diameter of 21 is about 65.97
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).
To find the diameter of a circle with a circumference of 66 inches, you can use the formula C = πd, where C is the circumference and d is the diameter. Rearranging the formula to solve for d, you get d = C / π. Plugging in the circumference of 66 inches, the diameter would be 66 / π ≈ 21 inches.

If a circle has a diameter of 21 feet the circumference is: 65.97 feet (diameter x Pi = circumference).
circumference = pi*diameter so diameter = circumference/pi = 4.456 inches
