It says so in the formula

Either pi times the diameter or pi times twice the radius (which is the diameter)

1. The formula for finding the Area of a circle is Pie X R-squared. R 3 cm squared is 9cm X 3,14 (value of Pie) = 28.26 square inches. 2. The formula for finding the Area of a rectangle is Length X Width (LXW): 14 X 2 = 28 square inches. 3.The answer is...900 ins. are in 75 ft. 24

Divide the area by pi then square root your answer which will give the radius of the circle and use 2*pi*radius to find the circumference.

You would have to round since area will not be able to be represented without rounding.
