Drawing a circle if radius is given

Let’s take an example

Draw a circle of radius 5 cm

Let’s follow these steps

1. Mark point O as center

       2. Since radius is 5 cm,

   we measure 5 cm using ruler and compass

3. Now keeping compass opened the same length.
   We keep pointed end at the center,
   and draw a circle using the pencil end of the compass.
   
   

   
   So, this is the required circle with center O

   and radius OP = 5 cm
