Circle O has a circumference of 220 meters. What is the approximate area of circle O? Show your work.

Answer 1

2 pi r = 220
so
r = 110/pi

A = pi r^2
A = pi (110)^2/pi^2 = 12100/pi = 3854 m^2

Answer 2

How would the area be 3845 m^2 is the cicumference is 220 m?

Answer 3

I understand your work now. However, when i divided 12100 by pi i got 3851.549623. If i rounded it would be 3852 m instead of 3845 m.

Answer 4

It said approximate so I used 3.14 for pi
