Question

A carpenter made a biggest cylindrical pillar from a cube of side 0.7mts.find the volume of the cylindrical pillar

Answer 1

Answer:

0.343 $m^3$

Step-by-step explanation:

Since the pillar is constructed from the cube, therefore, both shapes must have the same volume.

It is given that the side length of the cube = 0.7 m.

Volume of cube = $(Side)^3$.

Therefore, volume of cube = $(0.7)^3=0.343\:m^3$

Which means that also, the volume of the pillar = 0.343 $m^3$

Answer 2

Answer:

The volume of the cylindrical pillar = 0.2695 meter cube

Step-by-step explanation:

It is given that,

A carpenter made a biggest cylindrical pillar from a cube of side 0.7mts

Therefore the radius of cylinder r = 0.7/2 = 0.35mts and height h = 0.7 mts

Volume of cylinder

V = πr²h

To find the volume of cylindrical pillar

V =  πr²h

V = 3.14 x 0.35 x 0.35 x 0.7 = 0.2693 meter cube
