Indian sandstone circle sq meters - How to ascertain circle sq meters

[approach]

I have searched google, various supplier list selling Circle in Sandstone . Some with Squaring off kit and some without it

They all mentioned 1.8 diameter ,2.8 diameter, 3.6 diameter but not other details how it is laid and how much sq meter does it cover.

If someone can point out a way to calculated total square meter for let say 2.8 diameter circle and 2.8 diameter circle squaring off kit.

thnx

don't be mean to be rude, but trying rereading your own post!

you are asking people who give up their personal time to provide detailed and useful information on the current best practice in all aspects and types of paving, to calculate the area of a circle and the area of a square.

i.e. not as advanced as GCSE maths

Between 8 and 9m2 depending on the squaring kit you use.

At certain time of your life you have teach and share small and simple things which are hard for other person...

Thanks Pablo & Mickey_C

Area of a circle is the radius squared x pi

In your case a circle with a diameter of 2.8m would be about 6.2sq/metres.


To get this divide the diameter by 2 to get the radius
2.8 divide by 2= 1.4

Square it (Times 1.4 by itself)
1.4 x 1.4= 1.96

Now times by pi (3.142)
1.96 x 3.142= 6.15832

Which is roughly 6.2 sq/metres


A squaring kit would be a bit bigger and as Pablo has suggested would be 8 to 9 sq/metres.

area =pi r2
circumference is =2 pi r
