Answer:
A = 16pi
Step-by-step 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
Answer:
16π units^2
Step-by-step explanation:
C=π2r=π8
r=4
A=πr^2=π4^2=16π
