: How do I find the area of a circle with a circumference of 100 pi? How do I find the circumference if the area is 100 pi?
: All I have for information is that the area of a circle is A=(pi) (r^2) and that the circumference is is C=(2pi)(r)
Solve for r then plug it into the other equation.
What is the radius of a circle with circumference of 100 pi?
Then with that answer find the Area.
