how to find surface area of a circle

Let's Calculate Area of a Circumvolve

Area of a Circle Calculator

Area of a circumvolve is just, number of square units fit into a circumvolve.

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

Think, the input can simply exist in anxiety (ft), inches (in), yards (yd), centimetres (cm), millimetres (mm) and metres (m) but never a combination of two different units!

Surface area of a Circle = π 10 (Diameter/ii)^2
π = 3.142
Diameter (drop downwardly ft, in, yd, cm, mm, m)
Toll per unit of measurement (drop down ftⁱⁱ, in^two, yd^two, cm², mm^two, thou²)

Agreement the Square footage:

To sympathize how to calculate foursquare footage we must first brainstorm with the definition of area. An surface area is the size of a ii-dimensional surface. The surface area of a circle is the infinite independent within its circumference (outer perimeter). To discover 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 (1000).

The formula:
Area of a Circle = π x (Diameter/two)^2
π = 3.142
Answer = (π x (Diameter/ii)^2) foursquare expanse
Abbreviations of unit area: ft², in², yd², cmⁱⁱ, mm², yardⁱⁱ

Where do you lot need it in daily life?

Our Square Footage Calculator helps you summate the area required for making circular landscaping designs, carpeting, wall decals, center 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 assist users precisely measure things fifty-fifty 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 y'all demand 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 iii unknowns. You can use this formula in many real world examples such as when building a house, drilling, filling holes with physical etc. Essentially, the formula gives y'all authentic details on how much cloth yous need or how big the surface (you volition drill into) needs to be.

Nonetheless, you should as well be aware that the area of a circle calculator demands other things which you lot need to know before measuring.

Things Y'all Need To Have Care Nigh Measuring An Area Of A Circumvolve.

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

The circumference of a circle, however, is non that usually understood by many. Essentially, this variable tin exist defined every bit the distance effectually the circle or the entire length of the circuit along the circumvolve.

The π (pi) variable is basically a constant which cannot exist 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 permit y'all precisely calculate anything related to a circle. Even so, instead of doing things manually, at present you tin use our expanse of a circle calculator and make use of the ready circle formula.

Solve the Mutual Geometry Problem Today With Our Surface area Of A Circle Estimator.

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

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

Now, you can finally use and apply the Area Of A Circle figurer everywhere – and quickly go to the data you demand – without going in circles!

What measurements practice you need?

You demand to know the diameter of the circumvolve in either feet (ft), inches (in), yards (yd), centimetres (cm), millimetres (mm) or metres (thou).

What can you calculate with this tool?

You lot can summate the expanse of the circumvolve edge in foursquare feet, in foursquare inches, foursquare 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 take to do is enter the price per unit expanse and voila, yous have the total cost of materials in a unmarried click!
