Step-by-step
- V = πr²h = 3.1416 × 4² × 10 = 502.6548.
- Side surface = 2πrh = 251.3274.
- Total surface = 2πr² + 2πrh = 351.8584.
How to use this calculator
- Enter radius and height.
- Read volume + surface area + side area.
About this calculator
A cylinder has two circular ends and a rectangular wrap-around side (when "unrolled"). Volume V = πr²h — base area times height. Surface area: 2πr² (top + bottom circles) + 2πrh (lateral surface = circumference × height). Cylinders are everywhere: cans, pipes, water tanks, columns. The familiar "soda can" is ~6.6 cm diameter × 12.2 cm tall ≈ 355 mL.
Frequently asked
When unrolled, the cylinder side is a rectangle: width = circumference = 2πr; height = h. Area = 2πrh.
