Common math formulas

Common math formulas

  • Average
    sum/total number
  • Area of a circle
  • Circumference of a circle
  • Arc
    circumference(central angle/360)
  • Sector
    area(central angle/360)
  • Compound interest
    A = P (1 + r/n)^ (nt) A = accumulated amount P = principle r = interest rate expressed as decimal n = compounding per period t = number of periods
  • Exponential growth
    y = C(1+r)^t y = final amount C = initial amount r = rate of change t = time
  • Exponential decay
    y = C(1-r)^t y = final amount C = initial amount r = rate of change t = time
  • Cone volume
  • Cylinder volume
  • Cylinder surface area
  • Regular prism volume
  • Rectangular prism surface area
  • Rectangular pyramid volume
  • Sphere volume
  • equation of a circle
    (x-h)² + (y-k)² = r² h = x coordinate of the centre point k = y coordinate of the centre point
  • parabola standard form
    ax² + bx + c
  • Quadratic formula
    x = [-b ± √(b² - 4ac)}/2a
  • Rhombus area
  • Rhombus Perimeter
    2b + 2h
  • Trapezoid area
    A = (b1+b2)½h
  • Polygon interior angles
  • Ratio formula
    one part/another part
  • Direct proportional relationship
    one part/whole part = one part / whole part
  • Probability
    desired outcomes/total outcomes
  • Area of a triangle
  • Pythagorean Theorem
  • slope
    m = rise/run m = ∆y/∆x m = (y₂-y₁)/(x₂-x₁)
  • slope intercept form
  • % change
