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  
volume of pyramid   V=1/3(area of base)x height  
volume of sphere   V=4/3 x pi x r^2  
volume of prism   V=area of base x height  
volume of cylander   V=area of base x 2 x height  
volume of cube   V=length x base x height
