all you do is find the area of the circle... if you mean find the squares area, find the area of the circle, and then the square's area and subtract the squares area to the circles area
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
Area of a circle = pi*radius2
Find the area of the circle and divide by 4.
First find the area of the larger circle and then subtract the area of the smaller circle. Area=(pi x radiuslarger)-( pi x radiussmaller)
Area of a circle = pi*radius2
area of a circle = pi*r2
how do you find the area of a semi circle
Area of a circle = pi*radius2
You add the area of the square with the area of the semi circle.
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.
