 Description
 Formula
pi=   3.14
pythagorean theorem   A^2+B^2=C^2
area of triangle   A=1/2(base)x height
area of rectangle   A=length x width
area of trapezoid   A=1/2(sum of bases)x height
area of paralellogram   A=Base x height
area of circle   A=pi x r^2, If a circle has a radius of 4, its area is 3.14*4*4=50.24 If you know the diameter, the radius is 1/2 as large.

surface area of pyramid   SA=1/2(parimeter of base)x slant height + area of base
surface area of sphere   SA=4 x pi x r^2
surface area of prism   SA= sum of areas of the faces
surface area of cylinder   SA=circumfrence of base x height + 2(area of base)
surface area of cube   SA=6 x (length of edge)^2
volume of cone   V=1/3(area of base)x height
