Question 402742
rain which falls onto a flat rectangular surface of length 6 m and width 4 m is collected in a cylinder of internal radius 20 cm. What is the depth of water in the cylinder after a storm in which 1 cm of rain fell?
------------------
The volume of rain = 600 cm * 400 cm * 1 cm = 240000 cc
------------
Vol of cylinder = {{{pi*r^2*h = 400*pi*h = 240000}}}
{{{h = 240000/(400*pi)}}}
h =~ 190.99 cm
