# What is the formula for finding the the area of a square?

The formula for the area of a square is:

A=2S,

where

A=area

S= length of one side of the square

### What is the formula for finding the radius?

The formula for finding the radius of a circle is circumference divided by double of pi. If area is given instead of circumference, the radius may be found by dividing the area by pi, then finding the square root of the resultant quotient. It is also equal to half of the diameter, or the diameter divided by 2.

### What is the formula of finding the surface area of a square?

To find the surface area of a square you measure 1 side (people mainly choose the left side). Say that side was 6 inches. Then you know it is a square so all or the sides are equal. So the side adjacent to it (the top or bottom side) is also 6 inches. The side has to be adjacent to it or it won't work. Then you multiply the height by the length (6 *…
