Conical Frustum Calculator
Try an example:
Volume
7461.36 cm³
Total surface area: 2454.42 cm²
Slant height: 25.50 ·
Lateral area: 2003.63
— the slant height is too short for these two radii.
How it's calculated
Volume = (1/3)πh(R²+Rr+r²). Lateral surface area = π(R+r)×slant height. Total surface area adds the two circular ends: πR² + πr².
