Previous Similarity & Volume Next Circumference of a Circle & Pi
  • The volume of a sphere is proportional to the cube of the radius
  • The formula for the volume of a sphere is 4/3 * pi * r^3
  • Pi is an irrational number that represents the ratio of a circle's circumference to its diameter
  • The radius is the distance from the center of a sphere to any point on its surface
  • To find the radius of a sphere, you can rearrange the formula and solve for r
  • The formula for the radius is r = cube root of (3/4 * pi * volume)
  • Use the given volume to calculate the radius using a calculator
  • Use the pi button on the calculator instead of a rounded value for pi
  • The final answer should be rounded to three significant figures (SF)
