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.

SA=2πr2+2πrhSA = 2\pi r^2 + 2\pi r h
Surface area471.24 cm²

Pick the ○ next to the value you want to find, fill in the others, and it solves as you type.

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.
