A cylinder has two circular ends and a curved side. Volume = πr²h — the area of the circular base multiplied by the height.
Think of it as stacking a huge number of very thin circular discs on top of each other until you reach height h.
Remember
V = πr²h. The πr² part is the circle area formula — you already know that one. Just multiply by height.
Real World
A soup can is a cylinder. The volume tells you how much soup fits in it. Use V = πr²h with the radius and height of the can.
