# Calculator For Conical Frustum

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 = (r1-r2)2+h2
Where
s = Slant height
h = height

Volume of a Conical frustum :

V = (1/3)ph(r12+r22+(r1*r2))
Where
V = Volume
h = height

Lateral surface area of a Conical frustum:

L = p(r1+r2)s
Where
L = Lateral surface area
s = slant height

Base surface area of a Conical frustum:

B = pr12
Where
B = Base surface area

Top surface area of a Conical frustum:

T = pr22
Where
T = Top surface area

Total surface area of a Conical frustum:

A = p(r12+r22+(r1+r2)s)
Where
A = Total surface area
s = slant height

### How to use Conical frustum Calculator?

Step by step procedure for Conical frustum Calculator is as follows.

Step 1: Select which value you will be providing? Dropdown list has ( r1 (radius), r2 (radius), h (height)) ,( r1 (radius), r2 (radius), s (slant height) ) , ( r1 (radius), r2 (radius), V (Volume) ) , ( r1 (radius), r2 (radius), L (Lateral surface area) ) , ( r1 (radius), r2 (radius), A (Total surface area) ) options.

Step 2: Input appropriate value as per selected type in Step 1.
