If we want to calculate the time it takes to fill a water tank, we need the flow and volume of the tank.
The flow must be a data, but for the volume of the tank we need mathematics.
For example, if it is a cylinder, we need mathematics to know that the volume of the cylinder is:
V = pi * r ^ 2 * h
Answer:
c 1464 cm ^2 is the answer
