Problema Solution
A certain brand of gel is solid in a supermarket and comes in two kinds of containers, both of which are right circular cylinders. The taller container is twice the height of the other container, but its diameter is one-half that of the shorter container. If the shorter container costs 86.00 pesos and the taller container costs 46.00 pesos,which would you buy to have a better bargain?
Answer provided by our tutors
Volume of taller container =pi*(r/2)^2.2h.
=(pi*r^2h)/2
Volume of shorter contauner =pi*r^2 h.
Volume of taller conatiner(V) is half of the volume of shorter conatiner.
Unir rate of shorter conatainer =2V/86=V/43.
Unir rate of taller conatainer =V/46.
The unit cost of taller conatiner is less hence it is better to buy taler container.
