Find the surface area of a sphere with a radius of 10 in. Express your answer in terms of π.

400π in2

800π in2

500π in2

1,600π in2

Given:

Radius of the sphere = 10 in

To find:

The surface area of a sphere

Solution:

Surface area of sphere:

in²

The surface area of a sphere is 400π in².

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
