Answer 2

Answer:

There are many ways. The first is the easiest one needing only a circle, a ruler and a piece of thread.

Procedure:

1. Carefully place the thread on top of the circle, making sure the lines are aligned.

2. Mark the location where the circle ends (On the thread)

3. Measure the length of the thread from the start to the marking.

This is the perimeter of the circle (which is also called the circumference of the circle). However, if you want to know the formula, it is given below:

Let's consider,

R = Radius

D = Diameter

C = Circumference

π = 3.14

So,

C = πD

= Circumference = π x Diameter

OR

C = π x 2R = 2πR
