If c=12 pi, what is the area of the circle
To find the area of a circle, you use the formula A = πr^2, where r is the radius of the circle.
Since c = 2πr (circumference is equal to 2 times pi times the radius), we can rewrite c = 12π as
12π = 2πr.
Dividing both sides by 2π, we can solve for the radius:
r = 6.
Now, we can plug the radius back into the area formula:
A = π(6)^2
A = 36π
Therefore, the area of the circle is 36π square units.
