Formula:
The formulas used for calculating the circumference and area of a circle are:
- Circumference (C):
C = 2πrorC = πd - Area (A):
A = πr²
Where:
- π (Pi) ≈ 3.14159
- r represents the radius of the circle (distance from the center to any point on the edge).
- d represents the diameter of the circle (distance across the circle through its center,
d = 2r).
