Finding the Area of a Circle
How to find the area of a circle:
The area of a circle can be found by multiplying pi ¶ (which is equal to 3.14) by the square of the radius
If a circle has a radius of 4, its area is 3.14*4*4=50.24
If you know the diameter, the radius is 1/2 as large.

To find the area of a circle, you can use the formula:
A = π * r^2
Here's how it works:
1. Measure the radius (r) of the circle. The radius is the distance from the center of the circle to any point on its edge.
2. Square the radius by multiplying it by itself (r * r).
3. Multiply the squared radius by the mathematical constant π (pi), which is approximately 3.14159.
For example, let's say the radius of the circle is 5 units. The formula would be:
A = π * 5^2
A = 3.14159 * 25
A ≈ 78.54 square units
So, the area of the circle with a radius of 5 units is approximately 78.54 square units.
