# Surface area of a cylinder calculator

Finding the **area** of a **three-dimensional** shape or object is **not** an easy task as you have to be **familiar** with its properties. It will be **hard** to deal with such figures because you will get an **additional length**. A cylinder is one of those shapes that **students** normally find hard to deal with. It may also be **difficult** to calculate its surface area because of its **round** and long shape.

You can use the **surface area of a cylinder calculator** if you don’t want to do it manually. This **online** calculator can find the surface **area** of any cylinder with any measurement of its **radius** and height. Just **enter** the measure it asks for and this maths calculator will show you the final output. **Scroll** down to read about it in detail.

## What is surface area?

In **Mathematics**, the surface **area** is the **region** that is covered by any **object** or figure. **Simply**, it means the area that **comes** under the boundaries of the particular **figure** or **shape**. It can be calculated **easily** by using a simple and **specific** formula according to the **shape** as well as the given measurements.

### What is a cylinder?

It is a three-dimensional shape that has a **hollow** inner portion with **solid** boundaries or **sides**. A cylinder has **two** congruent surfaces that we **call** bases while its **height** is called the **lateral** surface that connects both **bases**.

Normally, a **cylinder** has a **round** shape at its **base** but it can also have a **rectangular** base. But this **maths** calculator is designed for **dealing** with regular or circular **cylinders** instead of rectangular cylinders.

This type of cylinder has two round **shapes** from both sides (**lower** and **upper**) while the **connecting** sides are straight **lines**. The length of its **vertical** sides will be **equal** to each other. In real **life**, we see many shapes in this **format** but may haven't **noticed** them. For example, soda **bottles**, cans, and straws are the **simplest** examples of cylinders.

### Surface area of the cylinder formula

As mentioned **earlier**, the cylinder has a **round** shape (**base area**) and **vertical** sides (lateral area). **So**, the total **area** will be the **sum** of these **areas** of a cylinder. Here is the **formula** to calculate the total area of a cylinder **quickly** within a few **steps**.

Area of a cylinder = 2𝝿r (r + h) square units

### How to calculate the surface area of a cylinder?

We can **easily** calculate the **surface** area of a cylinder using the above-mentioned **formula**. Here we have solved an example here to let you **understand** properly.

**Example 1:**

Find the area of a cylinder if the measure of its radius is **4** meters and its height is **8**

**Solution:**

As we know,

Area of a cylinder = 2𝝿r (r + h) square units

So, we have to put the given values in it.

= 2 (3.14) (4) (4 + 8) sq. meters

= 301.59 sq. m

### How to use the surface area of the cylinder calculator?

Sometimes, you may have bigger measurements for a **cylinder**. You can use this tool by Calculator’s Bag to deal with **such** problems. Here are the steps you need to **follow** for using this online calculator.

- Choose the units for input and output values
- Enter the measurement for the radius
- Insert the length of the height
- This calculator will automatically show you the total area of the cylinder.
