Question 3 of 10

Answer 1

Answer:

D. 300 m²

Explanation:

A sphere is a three dimensional object with a surface which as like that of a ball. A sphere is a set of points that are all at the same distance r from a given point in a three-dimensional space.

The surface area of a sphere is:

Surface area = 4πr²

where r is the radius of the sphere, π is a constant = 3

Given that r = 5 meters, hence substituting into the area equation:

Surface area = 4π(5)² = 4(3)(5)² = 300 m²
