Question

A circular rug has a circumference of 12.56 feet. What is the area of the rug? (Use 3.14 for .)
A.
6.28 square feet
B.
25.12 square feet
C.
56.52 square feet
D.
12.56 square feet

Answer 1

Unbelievably the same answer! Why? circumference is r * 2 * 3.14 = C
so i divided 12.56 with 3.14 = 4 / 2 = 2
the area of circle r^2 * 3.14 = A
2*2 = 4 * 3.14 is the same as circumference
