360 degrees/n

4

Sum of interior angles of any polygon

(N-2)x180 degrees

Where n is the number of sides

5

For a circle with radius

Circumference=2 pie
Area=pie r 2

6

Volume of a prism

Cross-sectional area x length

7

Volume of a cylinder

Area of circlexheight=pie r 2 h

8

Surface area of cylinder

2 pie r h + 2 pie 2

9

Compound growth and decay

N=N o (multiplier)n

10

Area of a sector

X degrees /360 degrees x area of a full circle

11

Length of an arc

X degrees / 360 degrees x circumference of full circle

12

Pythagoras theorem

A2 + b2 = c2

13

Trigonometry ratios :

Sin x : opposite/hypotenuse

Cos x : adjacent/hypotenuse


Tan x : opposite/adjacent

14

Compound measure for speed

Speed=distance/time

15
