# Hollow Cylinder Calculator

Posted by Dinesh onThis calculator calculates the **circumference (c1), circumference (c2), lateral surface area (l1), lateral surface area (l2), area (a),volume (v), thickness of the tube wall (t) ** using cylinder radius value (r1), cylinder radius value (r2), cylinder height (h) values.

## Hollow Cylinder Calculation

### Formula:

Circumference (C):

C1 = 2 π r1

C2 = 2 π r2

Lateral Surface Area (L):

L1 = 2 π r1 h

L2 = 2 π r2 h

Area (A):

A1 = π r1^{2}

A2 = π r2^{2}

A = A1 - A2

Volume (V):

V1 = π r1^{2} h

V2 = π r2^{2} h

V = V1 - V2

Thickness of the tube wall (t):

t = t1 - t2
