Hello,
First, let's state the formula for the area of a circle
Area = pi radius squared. Now we can plug in the numbers.
1250=3.14r^2 Divide both sides by 3.14
398.089=r^2 Now square root each side to give us:
radius = 19.95 inches (Note: these numbers are rounded off)
Hey--thanks for the expanded calculation of pi
