The Ultimate Student Study Sheet

Preparing for a geometry quiz on three-dimensional shapes? Keep these key identities handy:

MeasureFormulaUnits
Sphere VolumeV = (4/3)πr³cubic units (cm³, in³)
Sphere Surface AreaA = 4πr²square units (cm², in²)
Hemisphere VolumeV = (2/3)πr³cubic units
Solid Hemisphere AreaA = 3πr²square units
Sphere Volume Formula

Sphere Volume Formula

V = (4/3) × π × r³
Where V = Volume • r = Radius • π ≈ 3.14159265

Essential Mathematical Notation

  • V Volume of the sphere — The three-dimensional space enclosed within the spherical surface, measured in cubic units (e.g., cm³, m³, in³, ft³).
  • r Radius of the sphere — The straight-line distance from the exact center to any point on the outer surface (r = d / 2).
  • π Pi (π) — The mathematical circle constant, approximately 3.14159265 (or 22/7).
  • 4/3 Geometric Constant (4/3) — The rational coefficient derived from spherical calculus integration.
  • r³ Radius Cubed (r³) — The radius multiplied by itself three times (r × r × r), measuring 3D volume.
