In construction, circles are quite common. They are used for various purposes: in foundations, windows, during repairs. The calculator will help you quickly calculate the area of a circle. To do this, enter the values and get the result.
You need to enter data in meters, and the result is obtained in square meters – m². The proposed calculator calculates the area by radius, the formula is as follows:
S=πr²
Where:
- S – the desired area,
- r is the radius of the circle.
By diameter
If you need to calculate the area by diameter, then the calculator below will help.
The calculation formula in this case is:
S=π*d2/4
Where d is the diameter of the circle.
Let’s calculate the number of paving stones of popular size 100 * 200, for a round platform under a brazier with a diameter 6 meters.
We enter the value of 6 meters into the calculator for calculating the diameter and get – 28,26 sq. We translate centimeters into meters and calculate the area of uXNUMXbuXNUMXbone paving stone – 0,02 m².
It remains to divide the area of uXNUMXbuXNUMXbthe circle by paving stones: 28,26/0,02=1 pieces.
The circle calculator will help you to make calculations, just enter the required data and get the answer.
