Question

A cylinder has a height of 16 cm and a radius of 5 cm. A cone has a height of 12 cm and a radius of 4 cm. If the cone is placed inside the cylinder as shown, what is the volume of the air space surrounding the cone inside the cylinder? (Use 3.14 as an approximation of ‘pi’.)

Answer 1

For plato the correct option is C

Explanation:

C. 1,055.04 cm3

Answer 2

653.45 cm3

Explanation:

First calculate the volumes of both cylinders, the formula is pi x radius^2 x height.

so, big cylinder = 1256...cm3. small cylinder = 603...cm3

Then take away the large from small.

1256...-603...
