Can A and Can B are both right circular cylinders. The radius of Can A is twice the radius of Can B, while the height of Can A is half the height of Can B. If it costs $4.00 to fill Can B with a certain brand of gasoline, how much would it cost to completely fill Can A with the same brand of gasoline?

V(B) = PI*r^2*h
V(A) = PI*4r^2*h/2 = PI*2*rh

V(A) = 2 V(B)
