Cylinder Surface Area Calculator

Use this cylinder surface area calculator to compute total surface area and volume. Enter radius and height, then pick the unit you work with. A clear diagram shows radius and height at a glance. Clean steps and quick results for busy work.

Why Use Our Calculator?

You get accurate math with less effort. This cylinder surface area calculator adds helpful extras for clarity.

• Computes surface area and volume with standard formulas.
• Supports centimeters, meters, inches, feet, and millimeters.
• Shows a breakdown of bases and side area.
• Includes a cylinder diagram for easy reference.
• Fits homework, lab work, class work, and shop tasks.

The breakdown view is a unique extra for quick learning.

How It Works

The calculator uses these formulas. Surface area equals 2πr(r + h). Volume equals πr²h. Lateral area equals 2πrh. One base area equals πr². Here r means radius and h means height. Pi equals about 3.14159. We take utmost care with the formulas and rounding.

• Radius is the distance from the center to the edge of the base.
• Height is the straight line from the top circle to the bottom circle.
• Units set the label for your inputs and results.
• Use positive numbers for radius and height.
• Decimal values work for precise entries.
• Have a diameter only? Use half of it to get the radius.

Step-by-Step Instructions

1. Pick your unit.
2. Type the radius.
3. Type the height.
4. Select Calculate to run the math.
5. Press Enter in either field to run it.
6. Read surface area and volume in the results.
7. Open the breakdown to see each part.

Experience the Benefits

What the output shows

• Surface Area is the total outside area of the cylinder, in square units.
• Volume is the space inside the cylinder, in cubic units.
• Lateral Surface Area is the curved side area, excluding top and bottom.
• Two Bases is the combined area of the top and the bottom.
• Each value rounds to two decimals for a clean read.

Notes and limits

• Use the same unit for radius and height.
• The unit picker labels the results and keeps your inputs as entered.
• Enter positive numbers to get a result.
• This tool works for a right circular cylinder.
• Other shapes need different formulas.
• Rounding may change the last digit in some cases.

Examples and common uses

• Paint a drum. Use surface area to plan coverage.
• Wrap a mailing tube. Use lateral area to size the label.
• Fill a water tank. Use volume to plan capacity.
• Check homework or lab results with quick verification.

Quick example

• Radius 5 centimeters, height 10 centimeters.
• Surface area equals 150π which is 471.24 square centimeters.
• Volume equals 250π which is 785.40 cubic centimeters.
• Lateral area equals 100π which is 314.16 square centimeters.
• Two bases equal 50π which is 157.08 square centimeters.

Use this cylinder surface area calculator for clear results and less guesswork. Keep units consistent and values positive for smooth calculations.
