Suitable width to allow the padding to be securely fixed around each goal and behind post. The radius is also a straight line, with one end attached to the center point of the circle and the other to its boundary. Perfect Number Definition & Examples | What is a Perfect Number? This is because it uses a more accurate number for Pi, rather than rounding to 3.14. Keep in mind that a circle is an ellipse that has an equal distance from the center point to every side (the radius), so it does not matter where on the edge you measure to. The diameter of a circle is given as the length of a straight line that passes through the circle's center and has both of its ends attached to the boundary of the circle.
