Answer:
Step-by-step explanation:
Given
Represent volume with v, height with h and radius with r
Required
Determine the values of h and r that uses the least amount of material
Volume is calculated as:
Substitute 432π for V
Divide through by π
Make h the subject:
Surface Area (A) of a cylinder is calculated as thus:
Substitute for h in
Factorize:
To minimize, we have to differentiate both sides and set
Set
Divide through by
Cross Multiply
Divide through by 2
Take cube roots of both sides
Recall that:
Hence, the dimension that requires the least amount of material is when
