# How to Calculate the Area of ​​a Circle?

The process of calculating the area of ​​the circle, which is one of the most important shapes both in geometry and in our lives, is extremely important. The same formulas can be used in a simple mathematical operation as well as in an important engineering operation. We answered the question of how to calculate the area of ​​​​the circle and explained the formulas of the area of ​​​​the circle that you can use.

Even though it is used in different meanings in daily life, the circle is actually an important mathematical term. In geometry, it represents the area inside the circle. calculating the area of ​​a circle It can be a life saver in many ways. From a simple math exam, even in an engineering process with billions of dollars invested area of ​​the circle The calculation formula will work for you and will allow you to reach the result you are looking for.

Area of ​​the circle There are a few basic formulas you can use for the calculation process. These formulas change according to the value known about the circle. There are different formulas you can use to calculate the area of ​​a circle with radius, diameter, or circumference. With formulas that you will remember for the rest of your life once you learn it. how to calculate the area of ​​a circle We answered the question and talked about the website that has a ready-made calculation tool that you can use for this process.

## How to calculate the area of ​​​​the apartment?

• Calculating area of ​​circle with radius
• Calculating area of ​​circle with diameter
• Calculating the area of ​​a circle with the perimeter

## Calculating the area of ​​the circle with the radius:

• Step #1: Radius of the circle r is displayed as.
• Step #2: Formül; A = π x r2
• Step #3: Let the radius of the circle be 6 cm.
• Step #4: Let the number pi be 3.14.
• Step #5: A = π x r2  yani A = 3,14 x 62
• Step #6: A = 3,14 x 36
• Step #7: A = 113,04 cm2
• Step #8: Area of ​​the circle = 113.04 cm2
• Step #9: The operation is ok. If you have the radius of the circle as a known value for calculating the area of ​​the circle, you can easily reach the result by following the above steps with the formula A = π x r2. The number pi has trillions of digits, but In general, such transactions it is always calculated on the value of 3 or 3.14.

## Calculating the area of ​​the circle with the diameter:

• Step #1: Diameter of the circle d is displayed as.
• Step #2: Formül; A = π x d/22
• Step #3: Let the diameter of the circle be 20 cm.
• Step #4: Let the number pi be 3.14.
• Step #5: A = 3,14 x 20/22
• Step #6: A = 3,14 x 102
• Step #7: A = 3,14 x 100
• Step #8: A = 314 cm2
• Step #9: Area of ​​the circle = 314 cm2
• Step #10: The operation is ok. In the formula for calculating the area of ​​the circle with the diameter, we actually calculate the area of ​​the circle over the radius. Dividing the diameter in half We see the radius of the circle and continue the process over this value. The diameter of the circle is twice its radius.

## Calculating the area of ​​the circle with the perimeter:

• Step #1: Circumference of the circle C is displayed as.
• Step #2: Formula; A = C2 / 4π
• Step #3: Let the circumference of the circle be 42 cm.
• Step #4: Let the number pi be 3.14.
• Step #5: A = 422 / 4 x 3,14
• Step #6: A = 1764 / 12,56
• Step #7: A = 140,4 cm2
• Step #8: Area of ​​the circle = 140.4 cm2
• Step #9: The operation is ok. The process of calculating the area of ​​​​the circle with the circumference is according to the process of calculating the area of ​​​​the circle over the diameter and radius It consists of slightly more complex steps. However, once you understand the formula clearly and follow the steps carefully, it will be easy to reach the result.

• Step #1: From here Open the website with the circle area calculator.
• Step #2: Circumference You can calculate the area of ​​the circle by typing the circumference of the circle on the line.
• Step #3: Diameter You can find the area of ​​the circle by typing the diameter of the circle on the line.
• Step #4: Radius You can find the area of ​​the circle by typing the radius of the circle on the line.
• Step #5: The operation is ok. That’s why technology is beautiful. The area of ​​the circle, which you can find by working on it for minutes with the calculation formulas, thanks to the calculator You can access it with one click. You can also access formulas for other calculations on the site.

## Things to consider when calculating the area of ​​the circle: If you are using formulas instead of a website with a ready-made calculation tool for calculating the area of ​​the circle, here are some important points to consider. First of all, of course the value you know about the apartment you have to make sure it is diameter, radius or circumference. A little carelessness can cause the entire formula to be garbage.

The value given for the circle can be displayed in meters, centimeters or inches. In general, in our country, meters briefly m or centimeter for short cm although it is used if you are working with foreign sources may have a different display value. It is worth paying attention to because it will affect the numerical value of the transactions.

Another important point; area of ​​the apartment in square meters m2 or square centimeter cm2 is displayed as. Especially in exams with multiple choice answers. You should pay attention to this fine detail. Likewise, the pi number is generally calculated as 3.14. However, at some point in the question, it can be mentioned that you need to get a different value for the pi number. Therefore, it is useful to be careful at this point as well.

We answered the question of how to calculate the area of ​​​​the circle for you and for this process with formulas you can use together, we talked about the website with a ready-made calculation tool. Even if it is a ready-made tool, it will be much more useful and enjoyable to use formulas to exercise the brain.
