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.
