Sphere Formulas in terms of radius r: (Π = Pi)

• Calculate volume of a sphere:
  • V = (4/3) * Π * r^3
• Calculate the circumference of a sphere:
  • C = 2 * Π * r
• Calculate the surface area of a sphere:
  • A = 4 * Π * r^2

Sphere Calculations:

Use the following additional formulas along with the formulas above.

• Given the radius of a sphere calculate the volume, surface area and circumference
  Given r find V, A, C
  • use the formulas above
• Given the volume of a sphere calculate the radius, surface area and circumference
  Given V find r, A, C
  • r = cuberoot(3V / 4Π)
• Given the surface area of a sphere calculate the radius, volume and circumference
  Given A find r, V, C
  • r = √(A / 4Π)
• Given the circumference of a sphere calculate the radius, volume and surface area
  Given C find r, V, A
  • r = C / 2Π
