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 1.4m, calculate the cost of tin-coating at the rate of Rs. 3.50 per `1000\ c m^2`

Explanation

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

### Step 1: Understand the dimensions of the cylinder
- The radius of the base (r) = 70 cm
- The height of the cylinder (h) = 1.4 m

### Step 2: Convert the height to centimeters
Since the radius is given in centimeters, we need to convert the height from meters to centimeters:
