Question

What is the surface area of the sphere shown below with a radius of 8?

A. 683 sq. units
B. 85 sq. units
C. 256 sq. units
D. 64 sq. units

Answer 1

The surface area of the sphere is 256π square units option (C) 256π square units is correct.

What is a sphere?

It is defined as three-dimensional geometry when half-circle two-dimensional geometry is revolved around the diameter of the sphere that will form.

$\rm V = \dfrac{4}{3} \pi r^3$

We know the surface area of the sphere is:

SA = 4πr²

From the figure r = 8 units

SA = 4(π)(8)²

SA = 256π square units

Thus, the surface area of the sphere is 256π square units option (C) 256π square units is correct.
