A right circular cylinder has a volume of 90 cubic inches. Find the radius and height that will yield minimum surface area. I have already found the equation for volume and the surface area for this right circular cylinder in terms of radius "r" and height "h" for this problem which are: 1.)V=pir^2h 2.)SA with radius "r" and height "h"=2pir(h+r) I now need to find: 1.) The surface area of this right circular cylinder in terms of only radius "r", no height "h". 2.) The radius "r" and height "h" that minimize the surface area.

Hi there!

I need help with this question.

A right circular cylinder has a volume of 90 cubic inches. Find the radius and height that will yield minimum surface area.

I have already found the equation for volume and the surface area for this right circular cylinder in terms of radius "r" and height "h" for this problem which are:

1.)V=pir^2h

2.)SA with radius "r" and height "h"=2pir(h+r)

I now need to find:

1.) The surface area of this right circular cylinder in terms of only radius "r", no height "h".

2.) The radius "r" and height "h" that minimize the surface area.

Can you please help?

Thank You!
