: : 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.
: i.e.
: What is the radius of a circle with circumference of 100 pi?
: Then with that answer find the Area.
So, would that look like:
r=2pi divided by 100pi?
