🔵 **SUMMARY OF CIRCLE PROPERTIES** 🔍
**BACKGROUND KNOWLEDGE 📚**
Let's dive into the world of circles and number sets! 🔄🔢
🔴 **Circle Properties Highlights:**
1. **Radius (r):** Distance from the center to the edge.
2. **Diameter (d):** Twice the radius (d = 2r).
3. **Circumference (C):** The perimeter of the circle (C = πd or C = 2πr).
4. **Area (A):** Space enclosed by the circle (A = πr²).
5. **Sector:** A portion of the circle, like a slice of pizza.
6. **Chord:** A line connecting two points on the circle.
7. **Tangent:** A line touching the circle at one point.
8. **Secant:** A line intersecting the circle at two points.
🌐 **Number Sets Overview:**
1. **Natural Numbers (N):** 1, 2, 3, ...
2. **Whole Numbers (W):** 0, 1, 2, 3, ...
3. **Integers (Z):** ..., -3, -2, -1, 0, 1, 2, 3, ...
4. **Rational Numbers (Q):** Fractions and decimals.
5. **Irrational Numbers:** Non-repeating, non-terminating decimals.
6. **Real Numbers (R):** All rational and irrational numbers.
7. **Complex Numbers (C):** Involving the imaginary unit "i."
