The ratio of the volumes of two circular cylinders is $a:b$, and the ratio of their heights is $b:a$ .  Find the ratio of their radii.

The altitude of a circular cylinder is increased six times and the base area is decreased one-ninth of its value. The factor by which the lateral surface of the cylinder increases, is;

 A cylinder of diameter $d$ and height $h$ then its curved surface area in square units is

A metallic pipe whose inner diameter is $7 \mathrm{cm}$ , the external diameter being $14 \mathrm{cm}$ and has a height of $28 \mathrm{cm}$ . Find the volume of the metal.

Out of three jars of equal diameter and height $\frac{2}{3}$ part of the first, $\frac{2}{5}$ part of the second and $\frac{7}{9}$ part of the third were filled with dilute sulphuric acid. Whole of acid in the three jars were poured into a jar of $2.1 \mathrm{dcm}$ diameter. As a result the height of acid in the jar becomes $4.1 \mathrm{dcm}$. If the length of diameter of each of the three jars is $1.4 \mathrm{dcm}$, then let us calculate the height of the three jars.

It is required to fix a pipe such that water flowing through it at a speed of $7 \mathrm{m}/\min$, fills a tank with capacity $440 {\mathrm{m}}^3$ in $10$ minutes. The inner radius of the pipe should be:
