Essential Knowledge
Common Measurement Units
Length:
mm, cm, m, km • inches, feet, yards, miles
Angles:
degrees (°) • radians (rad) • gradians (gon)
Area:
mm², cm², m², km² • sq in, sq ft, acres
Volume:
mm³, cm³, m³, liters • cu in, cu ft, gallons
Essential Formulas
Circle:
Area = π × r² • Circumference = 2 × π × r
Rectangle:
Area = l × w • Perimeter = 2(l + w)
Triangle:
Area = ½ × b × h • Perimeter = a + b + c
Cylinder:
Volume = π × r² × h • Surface = 2π × r × (r + h)
