Combined Hemisphere & Cone
Interactive geometry — Volume & Surface Area of a Combined Solid (Hemisphere on Cone)
← Back to HomeFormulas
Cone Volume (Vc) = ⅓πr²h
Hemisphere Volume (Vh) = (2/3)πr³
Total Volume (V) = Vc + Vh
Cone CSA = πrl (l = slant height)
Hemisphere CSA = 2πr²
Total Surface Area = πr² + πrl + 2πr²
TSA Simplified = 3πr² + πrl
Slant Height (l) = √(r² + h²)
How to Use
• Drag to rotate the combined solid in 3D
• Scroll to zoom in / out
• Adjust sliders to change dimensions
• Watch measurements update in real-time
Key Terms
Combined Solid — a 3D shape made by joining two or more basic solids
Cone — the lower part tapering from the circular joint down to an apex
Hemisphere — half a sphere forming the domed top
Slant Height (l) — distance from apex to base edge of the cone
Did You Know?
The combined solid of a hemisphere on a cone is the classic ice cream cone shape! It also appears in rocket nose cones, decorative pillars, certain types of lampshades, and even in architecture for domed towers with conical spires.
