Answer 2

Given :

• Radius of the pipe = 21cm
• Height of the pipe = 90cm
• π = 22/7

To Find :

• Curved Surface Area of the pipe.

Formula :

• Curved Surface Area of Pipe = 2πrh

where,

• r = radius
• h = height

Solution :

Putting the Values :

• CSA of Pipe = 2πrh
• CSA of Pipe = 2 × 22/7 × 21 × 90
• CSA of Pipe = 2 × 22 × 3 × 90
• CSA of Pipe = 44 × 3 × 90
• CSA of Pipe = 44 × 270
• CSA of Pipe = 11,880cm²

Therefore :

• Curved Surface Area of the pipe is 11,880cm²
