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?
Answered by 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?

v= pie*r^2*h?
im very confused
please help me with this problem
