Question 419307
A diagram shows two similar cylinders. The radius of the smaller cylinder is half the raduis of the larger cylinder. The volume of the smaller cylinder is 200cm cubed. Find the volume of the larger cylinder.
-------------
If the heights are the same, the larger cylinder is 4x the volume = 800 cc
{{{V = pi*r^2*h}}}
{{{(2r)^2 = 4r^2}}}
Volume is a function of the square of the radius.
PS  It's pi, the Greek letter, not pie, the dessert.
