makes sense.thephoenix wrote:we are asked to find out the maximum volume of tank
with given parameters we can have
1)8as dia , and 10 and 12 as ht.
or 2) 10 as dia and 8 and 12 as ht
for 1 vol. of tank will be 16pi*10 or 16pi*12
for 2nd it will be 25pi*8 or 25pi*12
maximum vol is when dia is 10 and ht 12
so radius is 5
why not 12 as diameter..thephoenix wrote:we are asked to find out the maximum volume of tank

if you do the calculation, you will see that you get the biggest volume of the tank when diameter = 10.goyalsau wrote:
