Answer:
C
Step-by-step explanation:
The surface area (A) of a sphere is calculated as
A = 4πr² ← r is the radius, here r = 12, hence
A = 4π × 12²
= 4π × 144 = 576π units² → C
The surface area of the sphere is 576 square units. The correct option is B.
The space occupied by any two-dimensional figure in a plane is called the area. The area of the outer surface of any body is called as the surface area.
