The Circle: A Perfectly Round Marvel
Circles are everywhere! From the wheels on your bus to the ripples in a pond, they are an ever-present form in our universe. Mathematically, a circle is defined as the set of all points in a plane that are a fixed distance from a given point, the center.
Properties of a Circle:
- Radius (r): The distance from the center to the circumference.
- Diameter (d): Twice the radius, d = 2r.
- Circumference (C): The distance around the circle, calculated as C = 2πr.
- Area (A): The space inside a circle, calculated as A = πr2.
