Conical Frustum Formula

Equation for calculate conical frustum is,

Volume V = ( 1 / 3 ) π h ( r1² + r2² + ( r1 * r2 ) )
Slant Height S = √( ( r1 - r2 )² + h² )
Lateral Surface Area L = π ( r1 + r2 ) s
Top Surface Area T = π r1²
Base Surface Area B = π r2²
Total Surface Area A = π (r1² + r2² + (r1 * r2) * s)
