Maths Equations

Rectangle

Lenght x Width

Parralelogram

Base x Height

Triangle

1/2 x Base x Height

OR

1/2 x a x b x sin C

Trapezium

1/2 x (a + b) x h

Cuboid

Length x Width x Height

Prism

Area Of Cross Section x Length

Cylinder

π x (Radius Squared) x Height

Pyramid

1/3 x Area Of Base x Height

Speed

Speed = Distance / Time  (Specially Designed Toys)

Density

Density = Mass / Volume (Drink More Vodka)

Pressure

Pressure = Force / Area (People Fear Afros)

Circumference

π x Diameter OR  πD

Area

π x (radius x radius)

(a x a) + (b x b) = (c x c)

Sin

Sin = Opposite / Hypotoneuse 

S = O / H

Sine Rule - a / sin A = b / sin B = c / sin C

Cos

Cos = Adjacent / Hypotoneuse

C = A / H

Cosine Rule - a^2 = b^2 + c^2 - 2bc cos A

Tan

Tan = Opposite / Adjacent

T = O / A

x = -b (+ or -) /(b^2 - 4 x a x c)
