how to find area of circle


Let's Calculate Area of a Circle

Area of a Circle Calculator

Area of a circle is simply, number of square units fit into a circle.

Our circle area calculator, requires diameter OR radius of a circle to calculate area of a given circle.

Remember, the input can only be in feet (ft), inches (in), yards (yd), centimetres (cm), millimetres (mm) and metres (m) but never a combination of two different units!

Area of a Circle = π x (Diameter/2)^2
π = 3.142
Diameter (drop down ft, in, yd, cm, mm, m)
Price per unit (drop down ft2, in2, yd2, cm2, mm2, m2)



Understanding the Square footage:

To understand how to calculate square footage we must first begin with the definition of area. An area is the size of a two-dimensional surface. The area of a circle is the space contained within its circumference (outer perimeter). To find out the area of a circle, we need to know its diameter which is the length of its widest part. The diameter should be measured in feet (ft) for square footage calculations and if needed, converted to inches (in), yards (yd), centimetres (cm), millimetres (mm) and metres (m).

The formula:
Area of a Circle = π x (Diameter/2)^2
π = 3.142
Answer = (π x (Diameter/2)^2) square area
Abbreviations of unit area: ft2, in2, yd2, cm2, mm2, m2

Where do you need it in daily life?

Our Square Footage Calculator helps you calculate the area required for making circular landscaping designs, carpeting, wall decals, centre moulding on a ceiling and floor tiling.

Easily Find The Area Of A Circle (And Related Use Cases)

Technology has advanced and with that, there have been many calculators which help users precisely measure things even from the comfort of their laptop or mobile phone. Our area of circl calculator lets you easily find the area, circumference, radius or specific diameter of any circle.

All you need to do is fully understand the variables of this formula including the:

  • r (radius)
  • d (diameter)
  • C (circumference)
  • A (area)
  • π = pi = 3.1415926535898
  • √ = square root

With any of these variables (A, C, r or d) of a circle, you can precisely measure the other three unknowns. You can use this formula in many real world examples such as when building a house, drilling, filling holes with concrete etc. Essentially, the formula gives you accurate details on how much material you need or how big the surface (you will drill into) needs to be.

However, you should also be aware that the area of a circle calculator demands other things which you need to know before measuring.

Things You Need To Take Care About Measuring An Area Of A Circle.

Circles are complex shapes. Perhaps, their main variable is the radius – which is measured from the center of the circle to any of its sides. Essentially, the diameter is twice the radius – or any line that goes from one side of the circle to the other while crossing its center.

The circumference of a circle, however, is not that commonly understood by many. Essentially, this variable can be defined as the distance around the circle or the entire length of the circuit along the circle.

The π (pi) variable is basically a constant which cannot be expressed as a fraction but applies to all calculations – including the area of a circle calculator – whereas the √ (square foot) is basically the total surface within a circle.

Used since ancient geometrics, all of these variables let you precisely calculate anything related to a circle. However, instead of doing things manually, now you can use our area of a circle calculator and make use of the ready circle formula.

Solve the Common Geometry Problem Today With Our Area Of A Circle Calculator.

Whether you are in class solving a math test or need an accurate calculation about the area of a circle for a project that you are building, the formula for area of a circle is simple – but not that simple when you are left with a pen and paper.

This is why and how our Area Of A Circle Calculator can help you and instantly solve your questions. All you need is another variable to get the other three and solve the problem immediately.

Now, you can finally use and apply the Area Of A Circle calculator everywhere – and quickly get to the information you need – without going in circles!

What measurements do you need?

You need to know the diameter of the circle in either feet (ft), inches (in), yards (yd), centimetres (cm), millimetres (mm) or metres (m).

What can you calculate with this tool?

You can calculate the area of the circle border in square feet, in square inches, square yards, square centimetres, square millimetres and square meters. Yes, our tool is that awesome.

Our calculator gives you the option of calculating the exact cost of materials. All you have to do is enter the price per unit area and voila, you have the total cost of materials in a single click!

Conversion factors:

To convert among square feet, square inches, square yards, square centimetres, square millimetres and square meters you can utilize the following conversion table.

Square feet to square yards multiply ft2 by 0.11111 to get yd2
Square feet to square meters multiply ft2 by 0.092903 to get m2
Square yards to square feet multiply yd2 by 9 to get ft2
Square yards to square meters multiply yd2 by 0.836127 to get m2
Square meters to square feet multiply m2 by 10.7639 to get ft2
Square meters to square yards multiply m2 by 1.19599 to get yd2
Square meters to square millimetres multiply the m2 value by 1000000 to get mm2
Square meters to square centimetres multiply the m2 value by 10 000 to get cm2
Square centimetres to square metres multiply the cm2 value by 0.0001 to get mm2
Square centimetres to square millimetres multiply the cm2 value by 100 to get mm2
Square millimetres to square centimetres multiply the mm2 value by 0.000001 to get cm2
Square millimetres to square metres multiply the mm2 value by 1000000 to get m2
