Maths Eqts Flashcards
1
Q
Volume of prism
Volume of cylinder
A
Area of cross-section x length
Area of circle [x2]x length
2
Q
Arc length
A
Theta/360x 2piR
3
Q
Sector area
A
Theta/360 x pi R squared
4
Q
Area of a circle
A
Pi R squared
5
Q
Circumference of circle
A
2piR
6
Q
Units of length
A
1km = 1000 m 1m = 100 cm 1cm = 10 mm
7
Q
Units of area
A
1km squared = 1000m x 1000m
= 1.000.000m squared
1m squared = 100 x 100 cm = 10.000cm squared
8
Q
Volume
A
1km cubed = 1000m x 1000m x 1000m
1m squared = 100cm x 100cm x 100cm
9
Q
Capacity
A
1 litre = 100cl
1 litre = 1000ml
1litre = 1000 cm cubed
10
Q
Simple interest
A
I= PRT/100 A = I + P
11
Q
Compound interest
A
A = P x (1 + R/100) to the power of t I = A - P
12
Q
Rate of flow
A
Volume/time
