If the radius is 6 square feet, the surface area is 452.39

If the radius is 12, it's 1809.56

If the radius is 18, it's 4071.5

If the radius is 36, it's 16286.02

The are can be found from radius with the following formula
[tex]area = 4 \times \pi \times {r}^{2} [/tex]
To find the radius from area, use the formula rewritten like so
[tex]radius = \sqrt{ \frac{area}{4 \times \pi} } [/tex]
