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.
