find the surface area of a sphere with a radius of 10 m

The surface area (A) of a sphere is given by the formula:

A = 4πr^2

where r is the radius of the sphere.

Substituting the given radius of 10 m into the formula:

A = 4π(10)^2
A = 4π(100)
A = 400π

Therefore, the surface area of a sphere with a radius of 10 m is 400π square meters.
