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

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.
