The surface area of a sphere can be approximated as follows: Surface area = 4rv7;
where ris the radius of the sphere;
nis 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. 3,600 m2
B. 900 m2
C. 500 m2
D. 300 m2
