How do you find out diameter of 3 feet?

To find the diameter of a circle with a circumference of 3 feet, you can use the formula for the circumference, which is C = πd, where C is the circumference and d is the diameter. Rearranging this formula to solve for the diameter gives you d = C/π. Plugging in the values, the diameter would be approximately 3 feet / 3.14 ≈ 0.96 feet.
