Sections of cylindrical tubing are to be made from thin rectangular sheets that have an area of S = 600 in2. Find the radius r and height h needed to construct a tube that has a volume of 600 in3. (Round your answers to two decimal places.)
A) r= ? in
B) h= ? in
Thank you!

2pi r h = 600, so
pi rh = 300
pi r^2 h = pi rh * r = 300r = 600, so
r = 2
h = 150/pi
