How Do You Find the Volume of a Cylinder?

Find the volume of the cylinder shown in the diagram.

Summary

  1. The volume of a cylinder is V=Bh, where B stands for the area of the base and h stands for the height
  2. The base of a cylinder is always a circle
  3. The area of a circle is πr2

Notes

    1. The formula for the volume of a cylinder is V=Bh, where B stands for the area of the base and h stands for the height
    2. The base of a cylinder is always a circle
    1. r, the radius of the cylinder, is 6 in
    2. h, the height of the cylinder, is 9 in
    1. π is actually a non-repeating decimal that goes on forever, but for this problem we can round it to two decimal places
    1. Plug the values for π, r, and h into the formula for the volume of a cylinder
    2. Remember, r=6, h=9, and π=3.14
    1. We need to solve this for V:
    2. V=(3.14)(6)2(9)
    3. You can just follow the order of operations to simplify the right hand side
