The total surface area of a solid hemisphere of radius $$r$$ is given by

A reservoir is 3 m long, 2 m wide and 1 deep. Its capacity in litres is

The diameter of a sphere is 21 cm. Calculate its volume

The radius of a sphere is 3 cm. Its volume is:

A solid in the form of a cuboid is 4 cm x 3 cm x 2 cm. Its volume will be
(Note: cu cm $$=cm^3$$)

The curved surface area of a hemisphere of diameter $$2 r$$ is:

If the surface area of a sphere is $$ \displaystyle   324\pi cm^{2}   $$ then its volume is

If the volume in $$ \displaystyle  m ^{2} $$ and the surface area in $$ \displaystyle  m ^{2} $$ of a sphere are numerically equal then the radius of the sphere in m is

$$l \times b \times h$$ is formula of---

A toy box can fit $$36$$ equal sized unit blocks in it. Then its volume is
