The surface area of a sphere can be approximated as followed: 4(pi symbol)r^2 ; where r is the radius of the sphere; (pi symbol) is a constant that's roughly equal to 3. Using the approximation as told, calculate the surface area of a sphere with a radius of 2 meters. [the answers to choose from are: 9m^2, 24m^2, 16m^2, 40m^]
