The circumference of a circle can be calculated using the formula C = πd, where C is the circumference and d is the diameter. In this case, the diameter is given as 4 feet.

Using the formula, we can calculate the circumference C = π(4) = 4π feet.

Among the given options, the best estimation for the circumference would be 13 feet, as 4π is approximately equal to 12.57, which rounds to 13.

The circumference of a circle can be calculated using the formula C = πd, where C is the circumference and d is the diameter. In this case, the diameter is given as 3.25 meters.

Using the formula, we can calculate the circumference C = 3.14 * 3.25 = 10.205 meters.

Among the given options, the best estimation for the circumference would be 10.21 meters, as it is the closest value to the calculated circumference of 10.205 meters when rounded to the hundredths place.
