# 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.
