The correct question is <span>A cylinder has a volume of 320 pi in</span>³<span>. and a height of 5". Find the radius of the cylinder</span> we know that
[volume of a cylinder]=pi*r²*h----> r²=volume/(pi*h) r=√[volume/(pi*h)] volume=320*pi in³ h=5 in so r=√[320*pi/(pi*5)]--------> r=8 in
if you are going in a negative direction or by a decimal you are contracting, so the image would get smaller. If you are going in a positive direction(has to be a whole number as well) you have an expansion.
