How do you find the area of a circle?

The area of a circle is π (Pi) times the Radius squared, which is written:\t \t A = π × r2
Or, when you know the Diameter:
A = (π/4) × D2
Or, when you know the Circumference:
A = C2 / 4π

Area of a circle = Aπr²
*You multiply the area by pi and then by the square of the radius.
**If you are given the diameter instead of the area then just divide it by 2 and substitute it in the expression.
***If you are given the circumference then: A = C²/ 4π ;

To find the area of a circle, use the formula A = πr², where r is the radius. You can calculate the radius from the diameter by dividing it by 2. You can also find the area using the diameter or circumference with alternative formulas if needed.
