Cylinder Calculator
The Cylinder Calculator is a geometry tool used to calculate important properties of a cylinder such as volume, surface area, radius, and height. Cylinders are one of the most common 3D shapes found in real life, including objects like pipes, tanks, cans, and bottles.
This calculator simplifies complex mathematical formulas and provides quick, accurate results for students, engineers, architects, and designers working with cylindrical shapes.
What is a Cylinder Calculator?
A Cylinder Calculator helps determine:
- Volume of a cylinder
- Total surface area
- Lateral surface area
- Missing dimensions (radius or height)
It is based on standard geometric formulas involving π (pi), radius, and height.
Required Inputs
1. Radius (r)
Distance from center to edge of circular base.
2. Height (h)
Vertical length of the cylinder.
3. Optional Input
Depending on calculation type:
- Volume
- Surface area
- Radius or height (if missing)
Expected Output
The calculator provides:
- Volume (cubic units)
- Surface area (square units)
- Lateral surface area
- Missing dimension (if applicable)
Cylinder Volume Formula
V=πr2h
r
h
Abase=πr2≈28.27
V=πr2h≈226.19r = 3.0h = 8.0
Total Surface Area Formula
A=2πr(h+r)
Lateral Surface Area Formula
AL=2πrh
How to Use the Cylinder Calculator
Step 1: Enter Radius
Input the base radius of the cylinder.
Step 2: Enter Height
Input the vertical height.
Step 3: Select Calculation Type
Choose volume or surface area.
Step 4: Click Calculate
Get instant results.
Practical Example
Let’s assume:
- Radius = 3 cm
- Height = 10 cm
Step 1: Volume
V = π × 3² × 10
V ≈ 282.74 cm³
Step 2: Surface Area
A = 2π × 3 × (10 + 3)
A ≈ 245.04 cm²
