Question

Maria bought a swimming pool with a circumference of 24 feet. She wants to buy a cover for her pool. Maria will need to buy _______ square foot pool cover. Use 3.14 for pi.

A. 7.64
B. 11.99
C. 45.82
D. 183.28

Answer 1

C.45.82 is the answer

Answer 2

C. 45.82

Explanation:

We know the circumference is given by

C = 2 * pi *r

24 = 2 * 3.14 * r

24 = 6.28r

Divide each side by 6.28

24/6.28 = r

r = 3.821656051

We want to find the area

A = pi r^2

A =3.14 * (3.821656051) ^2

=45.85987261
