# Hollow Cylinder Calculator

A hollow cylinder, also known as a cylindrical shell, is a three-dimensional shape with two parallel circular bases connected by a curved surface. If you need to find the volume or surface area of a hollow cylinder, you can use a Hollow Cylinder Calculator. This tutorial will show you how to use a Hollow Cylinder Calculator and explain the formula used to find the volume and surface area of a hollow cylinder.

 Cylinder radius value (r1) m Cylinder radius value (r2) m Cylinder height (h) m
 Circumference (C1) = m Circumference (C2) = m Lateral Surface Area (L1) = m2 Lateral Surface Area (L2) = m2 Area (A) = m2 Volume (V) = m3 Thickness of the tube wall (t) = m

## Step 1: Input the Measurements

The first step in using a Hollow Cylinder Calculator is to input the measurements of the cylinder. You'll need to input the radius of the outer and inner circular bases and the height of the cylinder into the calculator. For example, if the outer radius is 5 cm, the inner radius is 3 cm, and the height is 10 cm, then you would input those values into the calculator.

## Step 2: Calculate the Volume

The next step is to calculate the volume of the hollow cylinder. The formula for the volume of a hollow cylinder is:

### Hollow Cylinder Volume Formula

Volume = πh(R2 - r2)

where π is pi (approximately 3.14), h is the height of the cylinder, R is the outer radius of the cylinder, and r is the inner radius of the cylinder.

Using our example values, the volume of the hollow cylinder can be calculated as follows:

Volume = π × 10(5^2 - 3^2)

Volume = π × 10(25 - 9)

Volume ≈ 1,395.6 cubic centimeters

## Step 3: Calculate the Surface Area

The final step is to calculate the surface area of the hollow cylinder. The formula for the surface area of a hollow cylinder is:

### Hollow Cylinder Surface Area Formula

Surface Area = 2πh(R + r)

where π is pi (approximately 3.14), h is the height of the cylinder, R is the outer radius of the cylinder, and r is the inner radius of the cylinder.

Using our example values, the surface area of the hollow cylinder can be calculated as follows:

Surface Area = 2π × 10(5 + 3)
Surface Area ≈ 376.99 square centimeters

## Conclusion

A Hollow Cylinder Calculator can save you time and effort in finding the volume and surface area of a hollow cylinder. By following the steps outlined in this tutorial and using the formulas for volume and surface area, you can easily calculate these measurements for any hollow cylinder.
