Find the volume of the largest right circular cone that can be fitted in cube whose edge is $2 \mathrm{a}$ units.

A solid is in the shape of a cone standing on a hemisphere with both their radii being equal to $1\mathrm{}\mathrm{c}\mathrm{m}$ and the height of the cone is equal to its radius. Find the volume of the solid in terms of $\mathrm{\pi }$.

A right angled triangle of which the sides containing the right angle are $6.3 \mathrm{c}\mathrm{m}$ and $10 \mathrm{c}\mathrm{m}$ in length, is made to turn round on the longer side. Find the volume of solid, thus generated. Also, find its curved surface area.

Volume of a right circular cone is $\frac{2200}{7} \mathrm{c}\mathrm{u}.\mathrm{c}\mathrm{m}$ and its diameter is $10 \mathrm{c}\mathrm{m}$. Find the slant height. Also find the curved surface area of cone in terms of $\mathrm{\pi }$.

$30$ circular plates, each of radius $14 \mathrm{c}\mathrm{m}$ and thickness $3 \mathrm{c}\mathrm{m}$ are placed one above the another to form a cylindrical solid. Find:
The total surface area

$30$ circular plates, each of radius $14 \mathrm{c}\mathrm{m}$ and thickness $3 \mathrm{c}\mathrm{m}$ are placed one above the another to form a cylindrical solid. Find:
Volume of the cylinder so formed.

A solid toy is in the form of a right circular cylinder surmounted by a right circular cone (as shown in fig). The diameter and height of the conical part is $24 \mathrm{c}\mathrm{m}$ and $16 \mathrm{c}\mathrm{m}$. The total height of the toy is $44 \mathrm{c}\mathrm{m}$. Find the TSA of the toy.
