Conical Frustum is the part of cone when it is cut by a plane into two parts. The upper part of cone remains same in shape but the bottom part makes a frustum. The line segment joining the two centers is the axis which denotes the height of the Conical frustum.

Frustum of cone is the part of cone when it is cut by a plane into two parts. The upper part of cone remains same in shape but the bottom part makes a frustum. The line segment joining the two centers is the axis which denotes the height of the Conical frustum. To Calculate all the properties of Conical frustum this calculator is helpfull.Using the following formula :-

** Slant height of a Conical frustum:**
s = √(r_{1}-r_{2})^{2}+h^{2}

Where

s = Slant height

r_{1} = radius

r_{2} = radius

h = height

**Volume of a Conical frustum :**
V = (1/3)ph(r_{1}^{2}+r_{2}^{2}+(r_{1}*r_{2}))

Where

V = Volume

r_{1} = radius

r_{2} = radius

h = height

** Lateral surface area of a Conical frustum:**
L = p(r_{1}+r_{2})s

Where

L = Lateral surface area

r_{1} = radius

r_{2} = radius

s = slant height

** Base surface area of a Conical frustum:**
B = pr_{1}^{2}

Where

B = Base surface area

r_{1} = radius

r_{2} = radius

** Top surface area of a Conical frustum:**
T = pr_{2}^{2}

Where

T = Top surface area

r_{1} = radius

r_{2} = radius

** Total surface area of a Conical frustum:**
A = p(r_{1}^{2}+r_{2}^{2}+(r_{1}+r_{2})s)

Where

A = Total surface area

r_{1} = radius

r_{2} = radius

s = slant height
