Question

What is the surface area of a sphere with a radius of 11 units?

A. 13317 units2
B. 3637 units2
C. 7267 units2
D. 48470 units2

Answer 1

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.

Please check question.

Answer 2

484
`\pi`

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`
