A circular swimming pool has a radius of 20 feet. A fence is going to be built so that there is a 4-foot space around the entire

pool. What is the length of the fence? Sunitha solved the problem as shown.
A circle with radius of 20 feet. A larger circle is 4 feet larger than the smaller circle. Radius = 24 feet. Circumference = 24 pi.

What was her error?
A) She should have used 12 in the formula, not 24.
B) She forgot to multiply the radius by 2 in the formula.
C) She did not add the additional fence length to the pool’s radius.
D) She should have used 4 ft in the formula.
