use this. A(area) = pi x r2 ( pi, which is 3.14 or 22/7, times the radius squared (r x r) )
Divide the circumference by 2*pi which then will give you the radius and use pi*radius2 to find the area of the circle
In order to find the area of a sector of a circle you can use the formula below: pi*r^2 * # of degrees/ 360
if it is the radius you can find area or circumference
Divide the area by pi then square root your answer which will give the radius of the circle and use 2*pi*radius to find the circumference.
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 use pi ( 3.14)To find the area of a circle you use this calculationpi x r x r.
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
The area of a circle with radius r is pi*r*r and its circumference is 2*pi*r Use the first to find r and then use that value of r in the second to find the circumference.
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.
To find area of a circle using diameter, you use this formuler. Area=pi(diameter/2)(diameter/2)
