I need help understanding how to calculate the area of a circle. What’s the formula, and can someone show a simple example?
 
To find the area of a circle, use the formula:

A = \pi r^2

where:

  • (A) is the area,
  • (\pi) (pi) is approximately 3.1416,
  • (r) is the radius (the distance from the center of the circle to its edge).
Example: If (r = 5),

A = pi (5)^2 = 25pi \approx 78.54
