Math's Formulas

Circles:

1. Circumference of a Circle ($C$): $C=2\pi r$ Where $r$ is the radius of the circle.

2. Area of a Circle ($A$): �=��2A=πr2 Where $r$ is the radius of the circle.

3. Arc Length ($L$): �=�360⋅2��L=360θ​⋅2πr Where $\theta$ is the central angle (in degrees) that subtends the arc.

Triangles:

1. Pythagoras' Theorem: �2+�2=�2a2+b…
