Water flows through a 2.3-cm-diameter hose at 4 m/s. How long, in minutes, will it take to fill a 750 L kiddie pool?

First find the volume of a 4 meter length of the pipe

V= phi x Radius x Radius x 400 (Radius is half the diameter)

We are using cm ... (4m =400 cm) so the answer will be in cc ... it will be more than 1200cc .... and this is how much water enters the pool every second.

remember 1000cc is a liter , (L)

Surely you mean "pi" ($\pi$), not "phi" ($\phi$).
