Area of a Circle Calculator
Are you trying to calculate the area of a circle manually and falling short each time? Do you often forget the formula for the surface area of a circle and wish there was an easier method? If your answers are all in the affirmative to this question, then you are in the right place.
With the area of a circle calculator, it is easy to solve math questions. You do not necessarily need to know the area of a circle formula. Filling in the required fields and clicking calculate automatically generates the answer.
The use of the calculator cuts beyond solving mathematical problems. It can also be used to solve real-life problems, like engineering and dressmaking.

What is an area of a circle calculator?
The area of circle calculator is an important mathematical software. It is used to calculate the surface of a circle, especially when the radius or diameter is known.
Calculating the area of a circle
Before going straight into the calculations, you need to know the basics. The basis of the calculations is essentially the formula and the definitions.
Calculating the area of a circle is not as difficult as you might presume. There are different methods of calculating. However, two main methods will be explained.
- Using the circumference of the circle.
- Using the diameter of the circle (area of a circle with diameter).
- Using the sector of a circle.
- Using the radius of a circle.
The diameter of a circle
The diameter of a circle is known as the line that crosses the centre of a figure, in this case, a circle. It also touches the margins.
The diameter of a circle is found by the multiplication of the circle’s radius. It is multiplied by 2. This means that the radius should be known or given before the diameter can be found. For easier representation,
Diameter = 2 × Radius.
Area of a circle diameter.
Using the diameter of a circle, the formula is
Area of a circle = π × (d/2)2.
The radius of a circle
On the other hand, the radius starts at the center of the circle and ends at the circle’s margin.
Area of a circle radius.
The formula for calculating the area of a circle using the radius of a circle is = π × r2.
The circumference of a circle
It is simply the linear distance around a circle. It can be used to calculate the area of a circle.
The sector of a circle
It is a part of a circle’s circumference. It is often pie-shaped and made from an arc and two radii.
For both formulae, the constant is π which is approximately 3.14 or 22/7.
How to use the area of a circle calculator
This section is dedicated to the usage of the area of a circle calculator. It would explain the required parameters and how to use them for your calculations.
With an area of a circle calculator, it is possible to calculate every parameter from the area of a circle to the diameter and then to the radius. All these are easily gotten without wasting time.
The fields in the calculator include
- Radius
- Pi
- Diameter
- Circumference
The following steps should be taken in using the area of a circle calculator.
- In calculating the area of a circle, the first thing to do is to look at your values. Check if you were given the radius or the diameter.
- The next step is to go ahead and type your values into the necessary field.
- Check out the results.
Importance of the area of a circle calculator
The area of a circle calculator is undoubtedly important. It forms the basis and foundation for several other equations. Besides that, it can be incorporated into several real-life events.
Some examples of real-life application to the area of a circle includes
- Using it to make fancy circle skirts.
- For landscaping purposes, especially if it is a circular area.
- For making tracks for athletes
- For the construction of roundabouts on the road
- It is used to construct a Ferris wheel in amusement parks.
- It is used for other circular parts like cylinders, gears, and much more.
Other mathematical uses of the area of a circle calculator include;
- It can be adapted to find the volume of a sphere.
- In calculating the area of a cone, you will need to get the area of a circle first.
Area of a Circle Calculator conclusion
While calculating the area of a circle manually might not need so many mathematical skills, it can be exhausting. Calculators, especially those fashioned for a particular issue, are the best bet.
The accuracy and speed with which it solves complex problems are top on the list of its importance. An area of a circle calculator is undoubtedly necessary.
