area and volume formulas

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
