Pythagoras' Theorem
2
Area of a Triangle
b = base
h = height
3
Circumference of a Circle
Circumference = pi x diameter
THINK!! * Cherry pies delicious *
4
Area of a Circle
where r = radius
THINK!! * Apple pies are too *
5
Formula Triangle for Histograms...
Or...Frequency = Frequency Density x Class Width
Or...Class Width = Frequency / Frequency Density
6
Speed, Distance, Time
So, Distance = Speed x Time
Speed = Distance / Time
Time = Distance / Speed
7
Density, Mass, Volume
So, Density = Mass / Volume
Mass = Density x Volume
Volume = Mass / Density

Trigonometry Ratios (Sin, Cos & Tan)
REMEMBER!! SOHCAHTOA
Sin (of angle) = Opposite / Hypotenuse
Cos (of angle) = Adjacent / Hypotenuse
Tan (of angle) = Opposite / Adjacent
