It helps immensely if you know the formula for the area of a sphere.
Area of a sphere = (4 π) (radius)² . . . . . for ANY sphere.
If the radius is 5-ft, then Area = (4 π) (5)² = 100 π = 314.16... square feet (rounded)

[latex]S \alpha = 4 \pi r^{2} \\ S \alpha = 4 \pi 5^{2} \\ S \alpha = 100 \pi \\ S \alpha = 314 ft^{2} ( aprrox.)[/latex]
