A cylindrical hole of diameter `30cm` is bored through a cuboidal wooden block with side `1 meter` Find the volume of the object so formed (`pi=3.14`)

Explanation

Given : diameter of cylinder hole is `30 cm a radius = 15 cm`

Cylindrical hole is bored through a cubical wooden bock with side` 1 m.`

`:. Height = 1 m = 100 cm`

Volume of the cylindrical hole` = 1/3 pi r^2h`

`= 1/3 x 3.14 x (15)^2(100)`

`= 1/3 x 314/100 x (15)^2 x 100`

`= 23550 cm^3`
