Question

find the volume of clay in a 2 m length of pipe with outer diameter 60 cm and inner diameter 20 cm.

Answer 1

Length or height of the pipe is 2m.

Outer diameter of the pipe is 60cm i.e 0.6m.

Inner diameter of the pipe is 20cm i.e 0.2m.

Therefore, outer radius .

Inner radius .

By calculating the volume of the pipe, we can find the volume of clay.

The formula for volume of the pipe is , .

Here are outer and inner radius respectively.

On substituting the values

.

So, the volume of the clay is
