The volume of such a can with base radius
and height
would be
We desire the base's circumference and the can's height to add to 120, i.e.
Substituting this into
allows us to reduce the volume to a function of a single variable
:
Taking the derivative with respect to
yields
Set this equal to 0 and find any critical points:
This suggests the can will have maximum volume when its radius is
cm, which would give a volume of about 20,371 sq. cm.
The answer is 6 because 12x6 is 72 and 16x3 is 48 and 48+24 is 72
Answer:
Step-by-step explanation:
Apply sum of cubes formula:
Answer:
£142 for 3 jumpers and 8 T-shirts
Step-by-step explanation:
Since the T-shirts cost £3.50 each and they are buy one get one free, when you buy 8 T-shirts you only pay for 4 of them.
£3.50(4) = £140 for the 8 T-shirts
Since you bought 3 jumpers with a buy 3 for £2 sale, the 3 jumpers cost £2.
Add the amount of money all together to find the total cost of the T-shirts and jumpers.
£140 + £2 = £142
