Find the volume of a Gulab jamun in the form of right circular cylinder with hemispherical ends whose total length is $2.7 \mathrm{cm}$ and the diameter of each hemispherical end is $0.7 \mathrm{cm}$

A juice seller was serving his customers using glasses. The inner diameter of the cylindrical glass was $5 \mathrm{cm},$ but the bottom of the glass had a hemispherical raised portion which reduced the capacity of the glass. If the height of glass was $10 \mathrm{cm}$, find what the apparent capacity of the glass was and what the actual capacity was. (Use $\mathrm{\pi }=3.14$)

A solid wooden toy is in the shape of a right circular cone mounted on a hemisphere. Height of the cone is $2 \mathrm{cm}$ and the diameter of base is $4 \mathrm{cm}$. If a right circular cylinder circumscribes the toy, if $k\pi c{m}^3$  more space will it cover? Find $k$
