Question

Explain with an activity :- volume of right circular cylinder ??​

Answer 1

Create right circular cylinder by providing radius for the base and height of the cylinder.

Click on button "Draw Cylinder" to draw cylinder.

Click on the cylinder to mark eight sectorial parts on it.

Click on each sectorial part to color them differently.

Click on the cylinder to cut apart the eight sectorial parts.

Click on each sectorial part sequentially from left. This will join all sectorial parts to form a cuboid.

Observations:

The segments approximately form a solid cuboid of height ‘h’, breadth 'r' and length 'П r'.

The volume of cuboid = length x breadth x height = l x b x h. = Пr X r X h = Пr2h

Hence, Volume of the cylinder = Пr2h
