The base radii and height of a cylinder and cone are equal if the volume of a cone is $9$cubic units then the volume of the cylinder is _____ cubic unit

Explain in detail about the shape of a cylinder and find the surface area of a cylinder whose radius of base is $2$ units and height of cylinder is $4$ units.

The formula used to find the total surface area of a right circular cylinder is

The height of a cylinder is $21 \mathrm{cm}$ and its curved surface area is $924 {\mathrm{cm}}^2$ . Find the radius of cylinder in centimetre. (Take $\pi =\frac{22}{7}$)

If width of a hollow cylinder is $2 \mathrm{cm}$, its internal diameter is $14 \mathrm{cm}$ and height is $26 \mathrm{cm}$. Both the ends of cylinder are open, then find the total surface area of the hollow cylinder in ${\mathrm{cm}}^2$.

$30800 {\mathrm{cm}}^3$ water can be filled in a cylindrical vessel. If its internal radius is $14 \mathrm{cm}$, then find its internal curved surface area in ${\mathrm{cm}}^2$.

Volume of _____ $=$ Area of circular base $\times$ Height.

Cylinders in which line segment joining the centres of the circular faces is perpendicular to the base are called _____ cylinders. $\left(\mathrm{right} \mathrm{circular}, \mathrm{right} \mathrm{cone}\right)$

Find the ratio of total surface area and curved surface area of a cylinder whose height and radius are $7.5 \mathrm{cm}$ and $3.5 \mathrm{cm}$ respectively.
