The circumference of a circle can be found using the formula C = πd, where C is the circumference and d is the diameter.
In this case, the diameter is 4 feet. Plugging it into the formula, we get C = π(4) = 4π feet.
The best estimation for the circumference from the given options is 13 feet, as it is the closest approximation to 4π.
To find the circumference of a circle, you can use the formula C = πd, where C represents the circumference and d represents the diameter. Given that the diameter is 4 feet, we can calculate the circumference.
C = πd
C = π * 4
C = 4π
Now we need to estimate the value of π. For simplicity, we can use the approximation π ≈ 3.14.
C ≈ 4 * 3.14
C ≈ 12.56
Therefore, the best estimation for the circumference of a circle with a diameter of 4 feet is 13 feet.
