Question

The radius of a circular pipe is 14cm. what length of tape is recquired to wrap it around the pipe once

take pi as 3.14

Answer 1

This is your answer.....

Given ::::
Radius of pipe = 14 cm.

If we wrap ... then it means that we cover the circumference...

So circumference = 2πr
= 2 × 3.14 × 14
= 87.92

But according to the question....

The tape is to be wrapped twice.....
so...

= 2 × 87.92
= 175.84 cm.

Hence the length of tape required is
175.84 m.
