The cone

Drag to turn and tilt the cone.

The cone opened up (its net)

Fan shape (green) = lateral surface. Circle (blue) = base. Both together = total surface.

📐 Cone Formulas

r = radius, h = height, l = slant height

Slant heightl = √(r² + h²)
VolumeV = 13 × π × r² × hspace inside, in cubic units
Lateral surface areaπ × r × lcurved side only, in square units
Base surface areaπ × r²bottom circle only, in square units
Total surface areaπ × r × l + π × r²side + base, in square units
