Area of a circle = pi*radius2 measured out in square units
for pi use this number 3.14159
and remember the radius of a circle = half the diameter.
----------------------------------------------------------------
Thus a circle with a 10 inch diameter would have an area of:
Radius = diamiter/2, which is 10/2= 5
3.14159 * (5*5) = 78.53975 square inches

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.
What is the area of a circle that has a radius of 5 cm?

How do you find the area of a shaded circle and the area of an unshaded circle on that is inside the other circle?
To find the area of the circle pi*radius*squared and subtract the area of the figure inside
Is the circumference and area of a circle the same?
The circumference of a circle is the distance arround the edge of the circle. The area of a circle is how big the inside of the circle is.
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.
