Question

The ratio of the radii of two cylinders whose heights is 2:3 . If the volume of the smaller cylinder is 32cm2 . Find the volume of the bigger one.

Answer 1

Answer:

The volume of the bigger one is 48 cm square

Answer 2

Answer:

108cm3

Step-by-step explanation:

Scale factor: 2/3

Hence, volume factor will be: (2/3)${3}$ =8/27.

Volume of small cylinder = 32cm3

Let big cylinder be 'B'

Volume of B = 27/8 x 32cm3

                     = 108cm3.

Thus, the volume of the bigger cylinder is 108cm3.

NB: The volume factor was inverted as a result of finding big cylinder, as using 8/27 would only have helped to find the volume of an even smaller cylinder.
