All About Circles
Circles are fascinating shapes with endless properties. In geometry, a circle is defined as the locus of all points in a plane that are at a given distance from a given point, the center.
The distance from the center of the circle to any point on it is called the radius.
Fun Facts About Circles
- The diameter of a circle is twice the length of its radius.
- The circumference is the distance around the circle and is calculated as C = 2πr, where r is the radius.
- Pi (π) is approximately 3.14159 and is a crucial part of calculations involving circles.
