## Conical Frustum Volume, Surface Area and Height Calculator

A conical frustum is a 3D solid formed by cutting a cone with a plane parallel to its base. It has two circular bases of different sizes connected by a curved surface. The volume, surface area, and height of a conical frustum can be calculated using the following formulas:

### Volume of a Conical Frustum

V = (1/3)πh(R^2 + r^2 + Rr)
• V: volume of the conical frustum
• h: height of the conical frustum
• R: radius of the larger circular base
• r: radius of the smaller circular base

### Surface Area of a Conical Frustum

A = π(R + r)l + π(R^2 + r^2)
• A: surface area of the conical frustum
• R: radius of the larger circular base
• r: radius of the smaller circular base
• l: slant height of the conical frustum

### Height of a Conical Frustum

h = (l^2 - (R - r)^2)^(1/2)
• h: height of the conical frustum
• R: radius of the larger circular base
• r: radius of the smaller circular base
• l: slant height of the conical frustum

Use our online calculator to find the volume, surface area, and height of a conical frustum. Enter the values for the upper radius, lower radius, and slant height, and the calculator will instantly display the results.
