FAQ
Frequently asked questions
What real-world objects are cylinders?
Cans, pipes, and tanks are common cylindrical shapes.
Does the surface area include the top and bottom?
Yes, this is the total surface area including both circular ends.
What if I only need the curved side area?
That's the surface area formula minus the two circular ends: 2πrh.
What units is volume in?
Your linear unit, cubed.
