Question

Find the surface area of the sphere. Leave your answers in terms of pi.

Radius = 100
Surface Area = [ ? ] pi

Answer 1

The formula for surface area of a sphere is: A = 4 x PI x r^2

Replace r with the given radius and calculate the area:

Area = 4 x PI x 100^2

Area = 4 x PI x 10,000

Area = 40,000PI
