Question

Find the volume of the cone​

Answer 1

The volume of the cone is 12936 cubic mm.

Explanation:

Given

Circumference of base = 132 mm

Height of the cone = 28 mm

Solution

Formula of circumference =
`2\pi r` = 132 mm

`\therefore\ r= (132)/(2 \pi ) = 21 mm`

Now volume of cone =
`(1)/(3) *\pi * r^(2) * h`

on substituting the value of r and h we get ;

`(1)/(3)*(22)/(7) *21*21*28= 12936\ mm`

thus volume of cone is 12936 cubic mm.
