Area of a Sector Fast!
To find the area of a sector, use this magic shortcut:
Area = (θ / 360) × π × r² where θ is the central angle!
Try with r = 10, θ = 45°!

Fast Area of a Parallelogram!
For area, just multiply the base × height. But here's the trick:
Area = a × b × sin(θ) where θ is the angle between them! Try for a = 5, b = 6, θ = 60°!

Find the Radius of a Circle from a Chord!
To find the radius of a circle from a chord and its distance from the center:
r = √[(d² + (c/2)²)], where d is the distance from center, and c is the chord length.
Try for c = 8, d = 6!

Rectangle Diagonal Trick!
Find the diagonal using:
d = √(L² + B²). But try this shortcut:
d = √(P²/16 - A). Try for A=24, P=20!

Cone Volume Shortcut!
Volume of a cone:
Volume = 1/3 × π × r² × h. Try r=5, h=10 for quick calculation!

Regular Polygon Area!
For a polygon with n sides and side length s, use:
Area = (n × s²) / (4 × tan(π/n)). Try with n=5, s=6!
