2 cylinders are proportional
the smaller cylinder has a radius of 4 centimeters, which is half as large as the radius of the larger cylinder. the volume of smaller cylinder =250 cubic cemtimeters.
what is the volume of the larger cylinder?

Math 
bobpursley,
radsmall/radiuslarge=heightsmall/heightlarge
volumesmall=250=PI*4^2(heighsmall)
volumelarge=?=PIradiuslarge^2*heightlarge
height small=250/16PI
Height large=?/64PI (radius large=8)
so put these into the proportion...
4/8=(250/16PI)/(?/64PI)
or
1/2=250*4/?
solve for?

brianna,
pl=3 &if i solve this problem in a proportion (which is what we've been working on in math) then what would be the point of trying to do the equation
v= pie*r^2*h?
im very confused
please help me with this problem
