Question
An engineering firm wants to construct a cylindrical structure that will maximize the volume for a given surface area. The following formulas are given for the volume and surface area of cylinders.
Volume (v) =
r2h
Surface Area (SA) = 2
rh = 2
r2

calculate the ratio of volume for cylinder A to volume for cylinder B?
- 1 : 3
- 2 : 3
- 1 : 1
- 3 : 2
Hint:
