The formula to find the area of a circle is: A = pi * r2

Area of a circle = pi*radius2

The formula to find the area of a circle is pi x the radius squared.

The formula to find area is you do the radius squared times pi or 3.14

The formula depends on the information available to you.

By using the formula: area of circle = pi*radius2

The radius of a circle is the distance from the center to any point on the circle. The area is the space within the circle. The formula to find the area is πr2. r stands for the radius of the circle. If you want to find the radius, you can work backwards from the area or the circumference, which is the perimeter of the circle. The formula for circumference is 2πr.

a formula is alway correct

Area = (pi) (R)2

-- Take the formula for the area of the circle in terms of the radius . . . A = (pi) R2-- Solve that formula for 'R'. You'll then have a formula for the radius in terms of the area,which is exactly what you're looking for.

The area of a circle = Pi*r2 where r is the radius and Pi is approximately equal to 3.14.
