Given the figure of a cone inside a cylinder

The volume of the space between the cylinder and the cone = the volume of the cylinder - the volume of the cone

The volume of the cylinder =


\pi\cdot r^2\cdot h

The volume of the cone =


(1)/(3)\cdot\pi\cdot r^2\cdot h

So, the volume of the space between them =


\pi\cdot r^2\cdot h-(1)/(3)\pi\cdot r^2\cdot h=(2)/(3)\pi\cdot r^2\cdot h

As shown in the figure: r = 4/2 = 2 in

h = 6 in

Let pi = 3.14

So, substitute with r, h, and pi

The volume of the space =


(2)/(3)\cdot3.14\cdot2^2\cdot6=50.24

Rounding to the nearest whole number

So, the answer will be option B) 50 in^3
