The volume of a right circular cylinder with its height equal to the radius is $25\frac{1}{7} {\mathrm{cm}}^3$. If the height of the cylinder is $h \mathrm{cm}$, then find the value of $h$. Take $\mathrm{\pi }=\frac{22}{7}$.

The ratio between the radius of the base and the height of a cylinder is $2:3$. If the volume of the cylinder is $12936 {\mathrm{cm}}^3$, then find the radius of the base of the cylinder.

If the radius is $k \mathrm{cm}$, find the value of $k$

The radii of two cylinders are in the ratio of $2:3$ and their heights are in the ratio of $5:3$. Find the ratio of their volumes.

If the ratio of volumes is $20:k$, then find $k$

If the area of the base of a right circular cone is $3850 {\mathrm{cm}}^2$ and its height is $84 \mathrm{cm}$, find the slant height of the cone.

If the length of the cone is $k \mathrm{cm}$, find $k$ 

A cylinder with base radius $8 \mathrm{cm}$ and height $2 \mathrm{cm}$ is melted to form a cone of height $6 \mathrm{cm}$. Calculate the radius of the base of the cone.

if the radius of the cone is $k \mathrm{cm}$, find $k$

The volume of a sphere is $4851 {\mathrm{cm}}^3$. Find its curved surface area.

If the curved surface area is $k {\mathrm{cm}}^2$ (Approximated to nearest integer.), find $k$ (Take $\pi =3.14$)

The curved surface area of a sphere is $5544 {\mathrm{cm}}^3$. Find its volume.

If the volume is $k {\mathrm{cm}}^3$, find $k$ ( Use $\pi =\frac{22}{7}$)
