Geometry Formulas:
- Area of Circle: A = πr²
- Circumference: C = 2πr
- Area of Rectangle: A = lw
- Area of Triangle: A = ½bh
- Pythagorean Theorem: a² + b² = c²
- Special Right Triangles (30-60-90 & 45-45-90 properties)
- Volume of Cylinder: V = πr²h
- Volume of Sphere: V = &frac43;πr³
- Volume of Cone: V = ⅓πr²h
- Volume of Prism: V = lwh
* Angles in degree measure = 360° / radians = 2π. Sum of interior triangles = 180°.
