Half the diameter then multiply the radius (your new measurement) by itself.
E.g
Diameter is 10 what is the area? 10 divided by 2 is 5 which is the radius. Multiply the 5 by itself. 52=25 then multiply the squared radius (25) by Pi.

By using the formula: area of circle = pi*radius2
Formula to find area for circle?
The area of a circle = Pi*r2 where r is the radius and Pi is approximately equal to 3.14.
How do you find the diamter of a circle if you know the area?
In order to find the diameter of a circle if you have the area is to rearrange the formula for the area of a circle to put diameter as the unknown, like so: PIE*d = Area of a Circle d = (Area of a Circle) / PIE Therefore if the area of your circle is 40cm, 40/PIE = 12.73cm and that's the diameter.

What is the radius and the area of a circle?
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.
