a = πr2
∴ r = √(a / π)
c = 2πr
∴ c = 2π√(a / π)
∴ c = 2√π2 √(a/π)
∴ c = 2√(π2a/π)
∴ c = 2√(πa)
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
The area of a circle can be found with the formula (pi)r^2
The area of a circle is π (Pi) times the Radius squared.
To find the circumference of a circle then multiply pi (3.14159265...) by the diameter of the circle. To find the area then multiply pi by the radius squared.
you times it by 3.14 but if you get a radius you timesit by 2, then by 3.14
Well first you find on your calculator you need to find pi which looks something like this π. Now to find the curcumference of any circle the formula is pi multiplied by the diameter. The radius is 16 metres, and the diameter of any circle in life is two multiplied by the radius. So you do π times by 32 which equals 100.53(I rounded it off to the nearest 2 decimal places). or even easier 3.14 x radius 2 l l l PI times raduis 2 and now for area 2 times 3.14 times raduis

15.70 meters Circumference = diameter x pi 5 meters x 3.14 15.70 meters
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
r=d/2 c=Pi*d 2*r=d c=Pi*2*r where c is the circumference r is the radius and d is the diameter
