How many $200$ ml measure of water will fill a 2 litre measure?

The volume of iron sphere and the volume of cylinder are numerically the same. Their radii are also the same. 

$\therefore$The height of cylinder$=$_____$\times \mathrm{radius}$

The volume of sphere is $288\pi c{m}^3$. The radius of the sphere is 

If the diameter of sphere is $12 cm$, then find the surface area and volume of the sphere.

Radius of a cylinder is equal to its height. If the radius is taken as ‘$r$’, the volume of the cylinder is $\mathrm{\pi }{r}^2\times r=\mathrm{\pi }{r}^3$. Like this find the volumes of the solids, with the following measures.

What is the ratio of the volumes of the cone, hemisphere, cylinder and the sphere?

How many cylinders of radius $3\mathrm{cm}$ and height $6\mathrm{cm}$ can be formed by melting sphere whose radius is $9\mathrm{cm}$?

A sphere of $6 \mathrm{cm}$ diameter is dropped into a cylindrical vessel of diameter $12 \mathrm{cm}$. Find the rise of water in the vessel in centimetre.

By melting a solid cylinder of radius 3 cm and height 20 cm, five spherical balls each of same size are formed. Find the radius of each ball. 

(A) 2 cm

(B) 3 cm 

(C) 4 cm 

(D) 5 cm
