Two cylindrical cans has the base of the same size. The diameter of each is 14cm. The height of one can is 10cm and another 20cm. Find the ratio of their volumes.
Volume of a cylinder=$$\pi r^{2}h$$
If both the cylinders have same radius then the only difference will be in their heights
Ratio of volumes will be in the ratio of their heights.
Therefore ratio of heights or volumes=10/20
=1:2
