**It costs Rs 2200 to paint the inner curved surface of a cylindrical vessel 10 m deep. If****the cost of painting is at the rate of Rs 20 per , find****(i) inner curved surface area of the vessel,****(ii) radius of the base,****(iii) capacity of the vessel.**

**Solution (i)**

Let inner curved surface area of a cylindrical vessel

It is given that it costs Rs 2200 to paint the inner curved surface of a cylindrical vessel at the rate of Rs 20 per .

Therefore,

Therefore, inner curved surface area of a cylindrical vessel is equal to 110 .

**Solution (ii)**

Let base radius of cylindrical vessel

Height of the cylindrical vessel **m**

Inner curved surface area

Therefore,

**m**

**Solution (iii)**

**Capacity of the cylindrical vessel**

=96.25
