- 1Math Test Revision 2014 Term 22H - Using Formulas
8A - Expanding Binomial Products
8B - Perfect Squares
5C - Area
5D - Composite Shapes
5E - Surface Area of prisms and pyramids
5F - Surface Area of a Cylinder
5G - Volume
5H - Volume of a Cylinder - 22H Using Formulas- Substituting values into Formulas -
Substitute the given values in the formula
S= a/1-r, when a=3 and r=0.4
S= a/1-r
S= 3/1-0.4
= 3/0.6
=5 - 32H Using Formulas- Transposing Formulas -
Transpose to make 'b' the subject
c=a(x+b)
c/a= x+b
c/a -x=b
b=c/a -x - 48A Expanding Binomial Products- Expanding Binomial Products -
(x + 3)(x + 5) =x +5x+3x+15
=x +8x+15 - 58B Perfect squares and the difference of perfect squares- Expanding Perfect Squares -
(x-2) = (x-2)(x-2)
=x -2x-2x+4
=x -2x+4 - 65C Area- Area -
Square = L
Rectangle = LxW
Triangle = 1/2 BxH
Circle = r
Trapezium = 1/2 (L+L)H
Rhombus = 1/2 (LxH)
Kite = 1/2 (LxH)
Parallelogram = HxL
Sector = r x - 75D Composite Shapes- Composite Shapes -
p= 2xL+W+1/2x2 r
= 2x17+14+1/2 x2 x7
= 34+14+ x7 - 85E Surface Area of prisms and pyramidsAdd up the area of every face on the shape
- 95F Surface Area of a Cylinder- Surface Area of a Cylinder -
TSA= 2 circles + 1 rectangle
= 2 r +2 rH - 105G Volume- Volume -
Rectangular Prism= LxWxH
Triangular Prism= (1/2 BxH)xL - 115H Volume of a Cylinder- Volume of a Cylinder -
V= r h
