The surface area (A) of a sphere is calculated using the formula:
\[ A = 4 \pi r^2 \]
where \( r \) is the radius of the sphere, and \( \pi \) is Pi, approximately equal to 3.14.
Given the radius \( r = 3.6 \) ft, we can plug the values into the formula:
\[ A = 4 \times 3.14 \times (3.6)^2 \]
\[ A = 4 \times 3.14 \times 12.96 \]
\[ A = 4 \times 3.14 \times 12.96 \]
\[ A = 4 \times 3.14 \times 12.96 \]
\[ A = 4 \times 3.14 \times 12.96 \]
\[ A = 4 \times 40.8384 \]
\[ A = 163.3536 \]
Now we round this to the nearest hundredth:
\[ A \approx 163.35 \] ft² (square feet)
So, the surface area is approximately 163.35 square feet.
