Answer:

300 square meters

Explanation:

The formula for surface area of a sphere is

A=4\pi r^2                .... (1)

where, r is the radius of the sphere and π is a constant that is roughly equal to 3.

It is given that the radius of the sphere is 5 meters..

Substitute π = 3 and r=5 in equation (1).

A=4\times (3)\times (5)^2

A=12\times 25

A=300

Therefore the surface area of a sphere with a radius of 5 meters is 300 square meters.
