Formulas
Volume (V) = πr²h
Curved Surface Area (CSA) = 2πrh
Base Area (B) = πr²
Total Surface Area (TSA) = 2πr² + 2πrh
How to Use
• Drag to rotate the cylinder in 3D
• Scroll to zoom in / out
• Adjust sliders to change dimensions
• Watch measurements update in real-time
Key Terms
Radius (r) — distance from center to edge of the circular base
Height (h) — perpendicular distance between the two bases
Axis — the line joining the centers of the two bases
Curved Surface — the lateral face connecting the two bases
Did You Know?
Cylinders are everywhere! Pipes, cans, batteries, and columns are all cylindrical because the shape offers high strength and efficient use of material for containing pressure or weight.
