To find the area of a circle, here is the formula:
A=Pi r2
To find area, you must square the radius and multiply it by pi. If it gives you the diameter, not the radius, divide the diameter by 2, that gives you the radius, then square it and multiply by pi.

How find the area of a square when a circle is inside?
You find the area of the whole square first. Then you find the area of the circle inside of it And then subtract the area of the circle from the area of the square and then you get the shaded area of the square

To find the area of the circle pi*radius*squared and subtract the area of the figure inside
How do you find the area of a circle if the circle is 8cm?
Area of a circle = pi*radius2
How do you find the area of a cirlcle?
The area of a circle is given by the formula A=pi x r2 Where A is the area of the circle, pi is a constant approximately equal to 3.1415, and r is the radius of the circle. So, to find the area of a circle with a radius of 5cm you would first square the radius -- 25 cm2. Then times by pi. So the answer would be 25pi cm2.
How do you calculate area of circle without radius?
Well, what you do is you would find the circumference, or the distance around the circle.

How do you find area of a circle with another circle in it?
First find the area of the larger circle and then subtract the area of the smaller circle. Area=(pi x radiuslarger)-( pi x radiussmaller)
How do you directly find the area of a circle?
area of a circle = pi*r2
Formula to find the area of circle?
Area of a circle = pi*radius2
Do you round your answer when you find the area of a circle?
You would have to round since area will not be able to be represented without rounding.
