Answer 1

Answer:

Step-by-step explanation:

The surface area of a sphere with radius r is given by

S = 4 pi r^2

for a radius of 11 units,

S =  4 pi 11^2 = 484 pi = 1520.5 sq. units

This does not correspond to any of the answers.

Answer 2

Answer:

484$\pi$

Step-by-step explanation:

Surface Area of Sphere Formula: 4$\pi$r$r^{2}$

When you plug it in it is 4$\pi$$11^2$

Then you would get 484$\pi$
