If a right circular cone of height $24\, cm$ has a volume of $1232\, cm^{3},$ then the area (in $cm^{2}$) of its curved surface is:

From a solid right circular cylinder with height $10 \ cm$ and radius of the base $6 \ cm$,a right circular cone of the same height and base is removed. The volume (in $cm^3$) of the remaining solid is

$A$ hemisphere and a cone have equal bases. If their heights are also equal,the ratio of their curved surfaces will be

Find the curved surface area (in $cm^{2}$) of a hemisphere of diameter $28\, cm$.

The volume of the largest right circular cone that can be cut out of a cube of edge $7 \, cm$ is.....$cm^3$

$A$ solid sphere of radius $1 \, cm$ is melted to convert into a wire of length $100 \, cm$. The radius of the wire (using $\sqrt{3} = 1.732$) is ......... $cm$.
