An interesting thing regarding derivatives and real world objects is that the derivative of a sphere's volume with respect to the radius corresponds to its total area. 

Considering that the volume of a sphere V can be computed as:

    V = 4/3 πr³,

where r is the radius of the sphere, we may conclude that the total area of V is given by:

A. 4πr²

B. 2πr

C. 4πr

D. 3/4 πr²

E. none of the above.
