oil cans x and y are right circular cylinders and the height and radius of y are each 10 times those of x . if the oil in can x filled to capacity sells for $ 1 , how much does the oil in y sell for if y is only half filled ?
"formula for vol of a cyl is pi * r ^ 2 * h so vy = 1000 * vy y when half filled will cost 500 times x so ans is c"
multiply(power(10, 1), 10)
