Question

the volume of a cylinder which exactly fits into a cube of side 4cm

Answer 1

Answer:

Step-by-step explanation:

Since, cube and cy.are of same size

Which means that radius of cy.= Side of cube

So, r of cy.=4cm

And also the height of cy =side of cube.

So, h of cy.=4cm

Since, vol of cy =πr2h

= 3.14x(4)^2x4

=3.14x16x4

=200.96cm^3

Answer 2

Answer:

volume of cylinder =  50.24 cm³

Step-by-step explanation:

Formula:-

Volume of cylinder with base radius 'r' and height 'h' is given by,

Volume V = πr²h

It is given that,

a cylinder which exactly fits into a cube of side 4cm

To find the radius of cylinder

Here the diameter of cylinder is equal to the side of cube.

diameter d = 4 cm

Therefore radius r = d/2 = 4/2 = 2 cm

To find the volume of cylinder

Here height of cylinder is equal to side of cube.

h =4cm

r = 2 cm

Volume V = πr²h

V = 3.14*2²*4 = 3.14*4*4 = 50.24 cm³

Therefore the volume of cylinder = 50.24 cm³
