Question

Find the area of the circle when C = π 8 . Give your answer in terms of π. PLEASE HELP

Answer 1

16π units^2

Explanation:

C=π2r=π8

r=4

A=πr^2=π4^2=16π

Answer 2

A = 16pi

Explanation:

The circumference of a circle is given by

C = 2 * pi *r

We are told the circumference is pi8

8pi = 2 * pi*r

Divide each side by 2pi

8pi/2pi = 2pir/2pi

4 =r

Now we want to find the area

A = pi r^2

A = pi(4)^2

A = 16pi
