Answer:
S.A = 804.4 ft
Step-by-step 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
