This could mean pressing a pen point down into paper or tying a string around a nail. Then tie a pencil, pen, crayon, or any other writing utensil at the other end of the string. The length of string will be the radius of the circle. Then, while pulling the pencil tight on the string, draw a circle.

Q. Is a sphere the perfect shape?
A perfect sphere is defined as being completely symmetrical around its center, with all points on the surface lying the same distance from the center point. While Earth is oftentimes referred to as a sphere, it actually just misses this classification because it is slightly squashed at the poles.
Q. Is there anything perfectly circular?
Perfect circles do not exist in nature, but you can see some close approximations around CMU’s main campus in Pittsburgh.
Q. How do you tell if a circle is a perfect circle?
For a circle to be perfect, we would need to measure an infinite number of points around the circle’s circumference to know for sure. Each point would need to be precise from the particle level to the molecular level, whether the circle is stationary or in motion, which makes determining perfection a tricky feat.
Q. What tool is used to draw big circles?
compass
Q. What is the best method to draw a circle in computer graphics?
So, to draw a circle on a computer screen we should always choose the nearest pixels from a printed pixel so as they could form an arc. There are two algorithm to do this: Mid-Point circle drawing algorithm. Bresenham’s circle drawing algorithm.
