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.

Divide your circumference by pi.

Diameter is 66 / 3.141592654 = 21 inches.
