Answer: A. 30
Step-by-step explanation:
The formula for the area of a circle is pi*r^2, where r is the radius of the circle.
900pi = pi*r^2
Divide both sides by pi.
900 = r^2
Square root both sides.
r = +/- 30.
Since the radius cannot be negative, the answer is 30 units.
I think that its 12.5 percent.
