Andrew bought 3 apple pies and 2 chocolate pies for $14.50. For $13 more, Kyra bought 5 apple pies and 4 chocolate pies. Which system of equations can be used to
find the cost of an apple pie, a, and the cost of a chocolate pie, c?

ΔV = 24*π   inches

Step-by-step explanation:

Amy Tube volume   =  V₁    the 6 inches sides will shape the circumference of area   A₁ = π*r²  

A₁ = π*(3)²    and

V₁ =  π*r²*h₁

V₁ = π*(3)²*8

V₁ = 72*π

In the case of Belinda, r will be 4 inches and h₂ = 6  and V₂

V₂ = A₂*h₂

V₂ =  π*(4)²*6

V₂ = 96* π

Then differences of the volumes is

V₂  -  V₁  =  ΔV = 96*π - 72*π

ΔV = 24*π   inches
