What is the surface area of a sphere?
The surface area of the sphere is calculated by the formula,
A = 4πr²
In terms of diameter - d;
A = 4π × (d/2)²
= 4π × d²/4
= πd² sq. inches
Calculation:
The given sphere has a diameter d = 10.4 inches
So, the surface area of the sphere is calculated by
A = πd²
= π × (10.4)²
= 108.16 π sq. inches
So, option b is correct.
