To find the area of a circle , you can use this simple formula:
Formula for Area of a Circle
Area=π×r2\text{Area}=\pi \times r^2Area=π×r2
Explanation:
- π\pi π (pi) is a constant approximately equal to 3.1416.
- rrr is the radius of the circle (the distance from the center to any point on the edge).
Steps to Calculate:
- Measure the radius of the circle.
- Square the radius (multiply the radius by itself).
- Multiply the squared radius by π\pi π.
Example:
If the radius r=5r=5r=5 units, then:
Area=π×52=3.1416×25=78.54 square units\text{Area}=\pi \times 5^2=3.1416\times 25=78.54\text{ square units}Area=π×52=3.1416×25=78.54 square units
