3D Cone Explorer

Formulas

Volume (V) = ⅓πr²h

Curved Surface Area (CSA) = πrl

Base Area (B) = πr²

Total Surface Area (TSA) = πr² + πrl

Slant Height (l) = √(r² + h²)

How to Use

• Drag to rotate the cone in 3D

• Scroll to zoom in / out

• Adjust sliders to change dimensions

• Watch measurements update in real-time

Key Terms

Apex — the pointed top of the cone

Base — the circular face at the bottom

Slant Height (l) — distance from apex to any point on the base edge

Lateral Surface — the curved face between apex and base

Did You Know?

Cones are one of the strongest shapes in nature — volcanic mountains, tornadoes, and even the human eye's cone cells use this efficient form. Traffic cones were invented in 1914!
