Answer:

Step-by-step explanation:
Given




Required
Find the height
The volume is calculated as thus:

This gives

Apply difference of two squares


Subtract 15 from both sides

Using a calculator to factorize, we have:

Split
or 
or 
x has complex roots for 
Hence:

Recall that:


The answer is:
17*(3/14)
More detailed;
3/14 gives us how many it takes to feed 1 person, then we times the amount it takes to feed one person by 17 (to get 17 people)
