Surface Area of a Cylinder Calculator
🧊 Volume & surface area (3D). Use the Surface area of a cylinder formula to find surface area, radius, height: pick the value you want, type the others, and the answer updates as you go.
Pick the ○ next to the value you want to find, fill in the others, and it solves as you type.
What each letter means
| Quantity | Unit |
|---|---|
| Surface area | cm² |
| Radius | cm |
| Height | cm |
Worked example
Find the surface area when Radius = 5 cm, Height = 10 cm.
Using SA = 2π r² + 2π r h: Surface area = 471.24 cm².
Frequently asked questions
What is the formula for Surface area of a cylinder?
SA = 2π r² + 2π r h.
What do the letters stand for, and what units are used?
Surface area in cm², Radius in cm, Height in cm.
How do you calculate surface area?
Put the values into SA = 2π r² + 2π r h. For example, with Radius = 5 cm, Height = 10 cm, surface area = 471.24 cm².
Can I solve for a different value?
Yes. In the calculator above, pick the circle next to any value (surface area, radius, height) and fill in the others: it rearranges the formula for you.
