#### Question

A cylinder and a cone have equal radii of their bases and equal heights. Show that their volumes are in the ratio 3:1.

#### Solution

Given that,

A cylinder and a cone have equal radii of their equal bases and heights

Let radius of cone=radius of cylinder=r

Let height of cone=height of cylinder=h

Let` V_1`=volume of cone

`V_2`=volume of cylinder

⇒` V_1/V_2=(1/3pir^2h)/(pir^2h)=1/3`

⇒ `V_2/V_1=3/1`

Hence their volumes are in the ratio 3 : 4.
