Question

Marcy is making a hooked circle-shaped rug for her mother. The circumference of the circle-shaped rug is 69.08 inches.

Answer 1

C=2pir
a=pir^2
69.08=c=2pir
divide both sides by 2
34.54=pir
divide both sides by pi
34.54/pi=r
sub that

a=pir^2
a=pi(34.54/pi)^2
a=(34.54^2)/pi
a=(34.54)/3.14
a=379.94

area of rug is 379.94 square inches

Answer 2

The answer to your question would be 216.9112.
