Answer:
area=100π
Step-by-step explanation:
circumference=2πr
20π=2πr
20=2r
r=10
area=πr^2
area=π10^2
area=100π
Answer:
The answer is 40π in.
Step-by-step explanation:
The way you can find circumference using radius is this formula below:
c= 2π*r
c=6.8*20
c=40π in.
I hope this helped. Good luck on the rest of your exam! :)
