Questions and Answers

What formula should be used to find the volume of a cylinder?

  • V = 2πrh
  • V = πr²h (correct)
  • V = πr³
  • V = 3.14r²h

    • If the height of the cylinder is doubled, what happens to the volume?

  • It remains the same
  • It becomes twice the original volume (correct)
  • It becomes 4 times the original volume
  • It becomes half of the original volume

    • What effect does doubling the radius of a cylinder have on its volume?

  • The volume remains the same
  • The volume becomes 2 times the original volume
  • The volume becomes 4 times the original volume (correct)
  • The volume becomes 8 times the original volume

    • If the value of π was mistakenly taken as 22/7 instead of 3.14, how would this affect the calculated volume?
