- 1Area of a CircleA = π r ^2
- 2Circumference of a CircleC = 2 π r
- 3Area of Compound ShapesDivide the shape into squares and rectangles, find their individual areas and then add them together.
- 4Interior Angles of Regular Polygons(n-2) × 180°
n = number of sides
Then divide by 'n' to find individual angles.
(If it is a irregular shape, then n=number of x/missing values) - 5Exterior Angles of Regular Polygons360 ÷ a
a = number of angles
All of the exterior angles of regular polygons = 360*
(If it is a irregular shape, then a=number of x/missing values) - 6y=mx+c equationsIf an equation of a line was Y=2x-4 it would mean that you would start at -4 on the Y axis (the one going up), you would find the points on the line by moving one to the right then two up. So your second point would be 1, -2 .
- 7Angles in parrallel linesvertically opposite: b=c
alternate: a=b
corresponding: a=c
supplementary: b+d=180 - 8Volume of 3D shapesprism: area of cross section (front face) x length
sphere: 4/3 π r^3
cone: 1/3 π r^2 h - 9Surface areasphere: 4 π r^2
cone: π r l - 10Area of trapezium1/2 (a+b) h
