Pipe Fitter Formula –
#Circle
Area = diameter x diameter x 0.7854,
Also, half of the circumference x half of the diameter
Also, Square of the circumference x 0.0795
#Arc
Length = degrees x Radius x 0.01745
Degrees =Length / Radius x 0.01745 Radius = Length / degrees x 0.01745
Circumference = Diameter x 3.1416
= Radius x 6.2831
Diameter = Radius x 2
=√(Area/0.7854)
= 1.1283 x square root of area
= Circumference x 0.31831
Radius = Circumference x 0.15915
= Square root of the area x 0.56419
Side of equal square = diameter x 0.8862
Side of inscribed square = diameter x 0.7071
Area of sector area of circle x no. of degrees in arc / 360
#Cone
Area of surface = one half of circumference of base x slant height + area of base
Volume = diameter x diameter x 0.7854 x one third of altitude
#Cube
Volume = width x height x length
#Cylinder
Area of surface = diameter x 3.142 x length x areas of the two bases
Area of base = Volume / Length
Length = Volume / area of base
Volume = diameter x diameter x 0.7854 x length
#Capacity in gallons
Area in inch x length (of stroke) in / 231
= (Diameter x diameter x 0.7854 x length) /231
= Diameter x diameter x length x 0.0034
#Ellipse
Area = short diameter x long diameter x 0.7854
#Hexagon
Area = width of side x 2.598 x width of side9.Parallelogram
Area = base x distance between the two parallel sides
#Pyramid
Area = ½ per meter of base x slant height + area of base
Volume = Area of base x 1/3 of the altitude
#Rectangle
Area = Length x Width
#Rectangular Prism
Volume = width x height x length
#Sphere
Area of surface = diameter x diameter x 3.1416
Side of inscribed cube = radius x 1.1547
Volume = diameter x diameter x diameter x 0.5236
#Square
#Triangle
#Trapezoid
Area one half of the sum of the parallel sides x the height
