Oil cans x and y are right circular cylinders and the height and radius of y are each 4 times those of x. If the oil in can x filled to capacity sells for $2, how much does the oil in y sell for if y is only half filled?  Select.
A) $60
B) $52
C) $63
D) $64
E) $68
formula for vol of a cyl is PI*r^2*h   so Vy = 64*Vy   y when half filled will cost 32 times x so ans is $64
