The surface area of a sphere can be approximated as follows:
surface area = 41v2;
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 7 meters.
o a. 84 m^2
ob. 588 m^2
o c. 14 m^2
o d. 1,372 m^2
