Question

INTERMEDIATE LEVEL
9. A conical funnel of diameter 23.2 cm and depth
42 cm contains water filled to the brim. The water
is poured into a cylindrical tin of diameter 16.2 cm.
If the tin must contain all the water, find its least
possible height

Answer 1

Step-by-step explanation:

By equating Volume of Cylinder and Volume of Cone, we get,

Vol (Cone) = Vol (Cylinder)

After putting in the values of radius and height of Cone and the radius of Cone, we are left with a variable i.e. the height of Cylinder

Solving the linear equation, we get the height of the Cylinder
