Question

IS
11. Again fill up the cone up to the brim and pour into the cylinder
still not full
iii. When the cone is filled up for the third time and emptied into the cylinder, observe
whether the cylinder is filled completely or not.
With the above experiment do you find any relation between the volume of the cone
and the volume of the cylinder?
We can say that three times the volume of a cone makes up the volume of cylinder,
which both have the same base and same height.
So the volume of a cone is one third of the volume of the cylinder.
.: Volume of a cone =
3
- รม
Turh
where 'r' is the radius of the base of cone and 'h' is its height.
Example-6. A corn cob (see fig), shaped like a cone, has the radius of its broadest end as
1.4 cm and length (height) as 12 cm. If each Icm of the surface of the cob carries an
average of four grains, find how many grains approximately you would find on the entire
cob.
