To find the area of a circle you take the square of the radius and multiply by pi.
The formula is = Radius2 x 3.14 = Area.
So, to find the radius, you reverse the formula. Divide 50.24 by pi, which equals 16. So Radius2 = 16. The which means the radius is the square root of 16, or 4.
Check your work, (4 x 4) x 3.14 = 50.24.
The radius is 4 inches.

How many cubic ft in a cylinder 20 inches diameter and 16 inches high?
To start with. find the volume by determining the area, then multiply by height. A diameter of 20 inches gives a radius of 10. Area is radius times radius, time pi. So 10x10= 100. x 3.14 is 3140. Times 16 is 5024. But that is cubic INCHES- to get cubic feet, divide 5024 by 1728 (number of cubic inches in a cubic foot.
What is the area of a circle with a 16 foot diameter?
3.14 x R2 (diameter)2 3.14 x 16= 5024 5024 x 5024= 2524056
What is the circumference of 40 inches?
Well this depends on If the radius is 40 inches or If 40 inches is the entire diameter. Circumference is determined using the formula Pi x Radius² Assuming 40 is only a radius it would be 3.14 x 40² or 3.14 x 1600 = 5024 inches If 40 inches is the entire diameter then its simply Pi x Diameter since the entire diameter is the radius squared. 3.14 x 40 = 125.6 inches.
