Study Notes
Circle Basics
- A circle is defined as a shape consisting of all points that are equidistant from a fixed center point.
Circumference
- The formula for calculating the circumference of a circle is ( C = 2\pi r ) or ( C = \pi d ), where ( C ) represents circumference, ( d ) is the diameter, and ( r ) is the radius.
Diameter
- The diameter is the line segment that passes through the center of the circle and connects two points on the circle. It is double the length of the radius.
Ratio of Circumference to Diameter
- The ratio of the circumference of a circle to its diameter is known as Pi (( \pi )), approximately equal to 3.14159.
