The surface area of a sphere can be approximated as follows: Surface area = 4πr2; where r is the radius of the sphere; π 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 2 meters. A 16 m2 B 9 m2 C24 m2 D 48 m2

Answer:

D. 48 [tex]m^2[/tex]

Explanation:

Since surface area = [tex]4\pi r^2[/tex] and r = 2 while [tex]\pi[/tex] = 3, the problem can be solved by simple substitution. Substitute for r and [tex]\pi[/tex]  in the equation

Surface area = 4 x 3 x 2 x 2

                         = 48 [tex]m^2[/tex]

The surface area of a sphere with a radius of 2 meters is 48 [tex]m^2[/tex].

The correct option is D.
