Question 3 of 10

The surface area of a sphere can be approximated as follows:
Surface area = 411/2;
where ris the radius of the sphere;
Ti is a constant that is roughly equal to 3.
Using the simple approximation above, calculate the surface area of a sphere
with a radius of 5 meters.
A. 500 m2
B. 900 m2
C. 3,600 m2
D. 300 m2

Answer 1

D. 300 m²

Step-by-step 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
