Question

Find the volume in cm³ of a length of pipe which has these measurements. Volume of a cylinder = πr²h π = 3.14

Answer 1

The complete data is:

The diameter of the pipe = 10 cm

The length of the pipe = 2 m

Given:

The diameter of the pipe = 10 cm

The length of the pipe = 2 m

To find:

The volume of the pipe

Solution:

Volume of pipe = Volume of cylinder = πr²h

From given, we have,

The diameter of the pipe = 10 cm

⇒ radius = r = d/2 = 10/2 = 5 cm

The length of the pipe = 2 m

⇒ height = h = 200 cm

Therefore, we have,

The Volume of pipe = πr²h

= π × 5² × 200

= 15,700 cm³

∴ The volume of pipe = 15,700 cm³
