Answer:

S.A = 804.4 ft

Explanation:

Given the following data;

Diameter of sphere = 16 ft

Radius = diameter/2

Radius, r = 16/2 = 8 ft

Pie, π = 3.142

To find the surface area of a sphere;

Mathematically, the surface area of a sphere is given by the formula;

S.A = 4πr²

Substituting into the formula, we have;

S.A = 4 * 3.142 * 8²

S.A = 12.568 * 64

S.A = 804.4 ft
