Asked by Helen
Suppose Cylinder A has the same height but twice the radius of Cylinder B. What is the ratio of the volume of Cylinder B to Cylinder A?

cylinder1:
height = h
radius = r
volume = pi r^2 h = pi r^2h
cylinder2:
height = h
radius = 2r
volume = pi (2r)^2 h
= 4pi r^2h
or
ratio is 1 : 4
so the volume is 4 times as large
height = h
radius = r
volume = pi r^2 h = pi r^2h
cylinder2:
height = h
radius = 2r
volume = pi (2r)^2 h
= 4pi r^2h
