Conical Frustum Calculator

This calculator computes the volume, surface area, and other properties of a conical frustum. The formulas used are:

• Slant height: $s = \\sqrt{(r_1 - r_2)^2 + h^2}$
• Volume: $V = \\frac{1}{3} \\pi h (r_1^2 + r_1 r_2 + r_2^2)$
• Lateral Surface Area: $L = \\pi (r_1 + r_2) s$
• Total Surface Area: $A = L + \\pi r_1^2 + \\pi r_2^2$
