Area:

• Rectangle:  A = bh

• Parallelogram:  A = bh

• Triangle:  A =  1/2 bh

• Circle:  A = πr2

• Cone:  A =  π x Diameter x Length ÷ 2

• Sphere:  A = π x Diameter²

Volume:

• Cylinder = πr²h

• Rectangular Solid = whd

• Pyramid = 1/3 x (Area of Base) x (Height)

• Cone =  1/3 x (Area of Base) x (Height)

• Sphere = 4πr³  / 3

• 1 Cubic inch = 1.804 Fluid Ounces

• Right Tri. Prism = 1/2 Base x Height

Surface Area:

• Total Surface Area = Sum of all Exterior Surfaces

• Prism = 2(wd + wh + dh)

• Cylinder = 2πrh + 2πr²

• Cone = πr² + πrs

• Sphere = 4πr²

Circumference:  C = πD

Mass = Volume x Density

Trigonometry:

• Right Triangles

  • SOHCAHTOA

• θ = angle

• sin θ= opposite / hypotenuse

• cos θ= adjacent / hypotenuse

• tan θ= opposite / adjacent

Pythagorean Theorem:

Right Triangles

a² + b² = c²

Conversion:

• Decimal Inches to Millimeters, multiply by 25.4

  2 in x 25.4 = 51mm
  .75 x 25.4 = 19mm

• Millimeters to Decimal Inches, divide by 25.4

  75mm ÷ 25.4 = 2.95 in

  10mm  ÷ 25.4 = .39 in

Physics:

• Density = mass/Volume; D = m/V

• Total Distance =  average velocity/time; d=vt

• Momentum = Mass * Velocity; p=mv

• Work = Force * Distance; W=Fd

• Power = Work / Time; P=W/t

• Energy Transfer = Mass * Specific Heat * Change in temp.
