**Reiny**, Wednesday, January 2, 2013 at 10:22amrolling along length:

height = 30, circumference = 18

2πr = 18

r = 9/π

volume = π(81/π^2)(30) = 2430/π

rolling along breadth

height = 18

circumf = 30

2πr = 30

r = 15/π

Volume = π(225/π^2)(18) = 4050/π

ratio of volume breadth : volume of height

=(4050/π) : 2430/π

= 5 : 3
