Question 338545
A cylinder of Volume 9 liters has a diameter and height which are equal. Fine the height of the cylinder.
----------------
{{{Vol = pi*r^2*h}}}
h = 2r
{{{Vol = pi*r^2*2r = 9000}}} 9 liters = 9000 cc (cubic centimeters)
{{{2pi*r^3 = 9000}}}
{{{r^3 = 4500/pi}}}
r =~ 11.2725 cm
h =~ 22.545 cm
