A cylindrical vessel, without lid, has to be tin-coated on its both sides. If the radius of the base is 70cm and its height is 1.4 m, calculate the cost of tin-coating at the rate of Rs. 3.50 per `1000c m^2dot`

Explanation

To solve the problem of calculating the cost of tin-coating a cylindrical vessel without a lid, follow these steps:

### Step 1: Understand the dimensions of the cylinder
- Given:
- Radius (r) = 70 cm
- Height (h) = 1.4 m = 140 cm (since 1 m = 100 cm)

### Step 2: Calculate the lateral surface area of the cylinder
