Cut circle using compasses
A circle is a perfectly even figure, from the center of which and to all its edges the distance is the same. This distance is called the radius of the circle. If the question is how to cut a circle out of paper, you can use an excellent stationery tool - compass.
This device, invented by mankind, has the appearance of two wooden or iron segments connected to each other. At one end of this segment is a pencil, and at the other - a sharp ending.Using this tool, you easily draw a circle of any diameter. I think you know how to cut a circle out of paper with scissors.

How to cut a circle without compass
If there is no compass on hand, then you can use the method that is often used when teaching children applications. For this you need a sheet of paper and scissors. Take the paper, and, if it is not square, bend it to make a square. Excess piece cut off. Now we bend a square shred in half, so that we get a triangle. Bend the triangle again and then again. The more such manipulations, the smoother the edges of the circle. But we will be enough two times. Now we take the scissors and cut the arc along the edge of the part with smooth movements.We expand the part, if everything is done correctly - it will turn out to be an even circle. Snowflakes are cut in the same way.

You should attach the stencil to a piece of paper or cardboard and fix its position. You can cut a circle around the contour with scissors or a knife. The disadvantage of the method is that it is difficult to determine where the center of the circle is, and that the stencil can slip off its place and the shape can be oblique.
