To find the area of a circle you use the formula A=pi*(radius*radius), but the given value is circumference, so you must first find the radius. To find the radius with the circumference given you use the formula C=2*pi*r, and solve r...
12pi=2*pi*r
12pi=2pi*r
6pi=r
With the radius you now can solve for the area. Which uses the formula A=pi*(radius*radius)...
A=pi*(6pi*6pi)
A=pi*(355.3057584)
A=355.3057584pi or 1116.22596
