Question

A circular rug has a circumference of 12.56 feet. What is the area of the rug? (Use 3.14 for .)

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
