Question 1098527
Water flows out a pipe at a rate of 40pi cm cube per second into an empty cylindrical container of base radius 4cm find the height of water in the container after 4 seconds.
--------
40pi cc/sec * 4 sec = 160*pi cc
============
Notice that including the units might help.
=============================
For the cylinder:
{{{Vol = pi*r^2*h = 160}}}
r = 4
{{{Vol = pi*16*h = 160*pi}}}
{{{h = 160*pi/(16*pi)}}}
h = 10 cm
