Area of sector = 60/360ths ie 1/6th of the total area;
Total area = 12 x 12 x 3.14 = 452.16 cm2
Area of sector = 452.16/6 = 75.36 cm2

The area of the square is 98 square cm. Assuming the shaded area is the remainder of the circle, its area is 55.9 square cm (approx).
The area is 40/360*pi*r^2 = 28.16 square cm.
no they don't
the area IS 38sq meters
The area of the shaded region is 1265.42 meters squared, since I subtracted the two totals of both the unshaded region and the shaded region of a circle.
You divide the area of the shaded region by the area of the full circle. For example, if the radius of the shaded region is 2 meters, the probability would be 4pi / 36pi, or 1/9. If the shaded region is a 'slice' of the circle, the chance is just the fraction of the circle which the 'slice' is.
Area of a circle with radius r = pir2Area of the largest circle = Area of the smallest circle + Area of the shaded regionSince areas of the smallest circle and the shaded region are 9pi and 72pi, the Area, A, of the largest circle isA = 9pi + 72pi = 81pi, where r2 = 81.Thus, the radius of the largest circle is 9
Find the area of the shaded sector. radius of 3 ...A+ = 7.07
(pi * radius squared) * ( sector angle / 360 )
A circle with a radius of 135 units has an area of 57,255.53 square units.

0. There is no circle so no shaded area of a circle!
The area of the shaded region can be gotten by multiplying the area of the circle by the subtended angle of the sector.
We would need to know how big the circle is. And what is the shaded part looks like. That will help us figure out the answer.
It is: 110/360*pi*12*12 = 44*pi square units
Since there is no shaded part, the answer must be that its area is 0 square units.
