The square footage of a radius is meaningless, but if you mean the square footage of a circle of radius say R, the answer is 3.142 x R x R
The total surface area (including the "top" and "bottom" is 2*pi*r*(r+h) = 136.83 sq ft, approx.
Multiply by 144.
The radius of a circle with an area of 706.50 square inches is: 15 inches.
To find the volume of the column, you need to first find the area of the cross-section. In this case the radius is 1.5 feet. Thus the area is pi1.52. The volume is this area multiplied by 12, so the volume comes out at 12pi1.52 which can be simplified to 27pi. Thus the square footage of the column is 27pi ft2 or approximately 84.823 ft2
That quantity is usually called "area".The area of any circle is (pi) (radius)2 .Area = (pi) (11 inches)2 = 380.133 square inches (rounded)To convert square inchage to square footage, divide by 144.380.133 square inches = 2.64 square feet (rounded)

This will depend on which column you are looking at. You can use the formula in order to find out the answer.

The radius of a circle with an area of 35 square inches is 3.34 inches.
The radius of a circle with an area of 706.50 square inches is: 15 inches.

A circle with a radius of 26 inches has an area of: 2,124 square inches.
Surface area for a circle is pi * radius squared If the diameter is 25 feet, then the radius is 12.5 feet, and the square footage is pi * 12.5 * 12.5 Or about 491 square feet
