Answer:
Area = 121pi sq cm
Explanation:
Circumference is the distance around the circle. The formula for circumference is:
C = pi•d
The question has the info in it that the circumference is 22pi.
C = 22pi
remember,
C = pi•d this means that the circle has a diameter (the d in the formula is diameter) 22cm.
The radius is half the diameter. The diameter is 22cm, so the radius is 11cm.
The formula for the area is:
Area = pi•r^2
= pi•11^2
= pi•121
= 121pi
The area is 121pi sq cm.
