Cylinders

A cylinder has two parallel circular bases and a curved surface. The perpendicular distance between the two bases is the _____ of cylinder.

What is the volume of a cylindrical shape water container, that has a height of $7\mathrm{cm}$ and diameter of $10\mathrm{cm}$?

Find the surface area of a solid cylinder with radius $2.5 \mathrm{cm}$ and height $7.3 \mathrm{cm}$.             [Enter the value excluding units and up to three significant figures]

If the radius of cylinder is doubled and its curved surface area is not changed, then its height must have to be

The curved surface area of a cylinder of height $21 \mathrm{cm}$ is $462 {\mathrm{cm}}^2$. Its diameter (in $\mathrm{cm}$) is:
