A metal pipe is 77 cm long. The inner diameter of a cross section is 4 cm, the outer diameter being 4.4 cm.  Find its(i) inner curved surface area,(ii) outer curved surface area,(iii) total surface area

Explanation

To solve the problem step by step, we will find the inner curved surface area, outer curved surface area, and total surface area of the metal pipe.

### Given Data:
- Length of the pipe (h) = 77 cm
- Inner diameter (d1) = 4 cm
- Outer diameter (d2) = 4.4 cm

### Step 1: Calculate the Inner Radius (R1) and Outer Radius (R2)
