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

C. 45.82

Step-by-step 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

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
