Question

Marcy is making a hooked circle-shaped rug for her mother. The circumference of the circle-shaped rug is 56.52 inches.

What is the area of the rug? (Use 3.14 for .)
A.
28.26 in2
B.
154.34 in2
C.
254.34 in2
D.
508.68 in2

Answer 1

It’s C. Since we know that the radius is 9, we need to plug it into the formula.

Area = Pi*R^2
Area = 3.14*9^2
Area = 3.14*81
Area = 254.34 or C

Answer 2

A

Explanation:

to find the area of a circle you need to multiply the radius by pie (3.14)

56.52 ÷ 3.14 = 18

18 ÷ 2 = 9

9 ⋅ 3.14 = 28.26
