50 feet
25 feet
6 feet
13 feet

answered
The circumference of a circle can be calculated using the formula C = πd, where C is the circumference and d is the diameter.
Given that the diameter is 4 ft, we can substitute this value into the formula:
C = π * 4 ft
C ≈ 12.57 ft
Out of the given options, 13 feet is the best estimation for the circumference as it is the closest estimate to the calculated value of 12.57 feet.

To find the circumference of a circle, you can use the formula: C = πd or C = 2πr, where C is the circumference, d is the diameter, and r is the radius.
Given that the diameter of the circle is 4 feet, we can use the formula C = πd to find the circumference.
Using the value of π as approximately 3.14, we have C = 3.14 * 4 = 12.56 feet.
Comparing the options provided, the nearest estimation to the calculated circumference of 12.56 feet is 13 feet. Therefore, the best estimation for the circumference of this circle would be 13 feet.

To find the circumference of a circle, we can use the formula:
C = π * d
where C is the circumference and d is the diameter of the circle.
In this case, the diameter is given as 4 feet.
Therefore, we can substitute this value into the formula:
C = π * 4
C ≈ 3.14 * 4
C ≈ 12.56 feet
Since none of the options are exactly 12.56 feet, we must select the closest estimation, which is 13 feet.
