radius = diameter/2 = 24 kilometers/2 = 12 kilometers Area of circle = πr2 = 3.1415 x 122 square kilometers = 452.376 square kilometers

It is difficult to say since there is no image and it is not clear what part is shaded. But, if there is a circle with a 12 metre diameter which contains two equal circles which are as large as possible, then the shaded area is probably 56.55 square metres.
The area of a circle with a diameter of 9.4 m is: 69.4 m2
If the area of a circle is 8pi, its diameter is: 5.657 units.
Area of the circle = 16*pi square units
radius = diameter/2 = 24 kilometers/2 = 12 kilometers Area of circle = πr2 = 3.1415 x 122 square kilometers = 452.376 square kilometers
Every diameter of the same circle is the same length, and unless someone comes alongand stretches the circle when you're not looking, the diameter doesn't change.So...YES-----------I disagree...No they are not... all circles would be the same size if that were the case.What remains a constant is that all circles are 360 degrees.==================================The question doesn't ask about " ... the diameter of circles ... ".It asks about " ... the diameter of a circle ... ".The diameter of circles is not always the same, butthe diameter of any one circle is always the same.P.S.: This is not the place to debate the answer.The "discussion area" is.
it would be the diameter of the smaller circle times sqrt 2
-6
The area would be 5,027 square km
Area of the circle = pi*r2 = 3.14159*3.5*3.5 = 38.48 square km

No. You can only define a circle by radius, diameter, area, perimeter. Concentric circles have the same centre, therefore, if they were the same circles with the same radius, then they would all lie on top of each other and be effectively one circle.
The circumference of a circle of 7 inches is: about 21.99 inches. You can easily do this calculation for other circles by multiplying the diameter by Pi (about 3.1416).
The area of a circle with 6 meters diameter is 9xpi square meters. The area of circles with 4 meters diameter and 2 meters diameter are 4xpi and 1xpi square meters respectively. The combined area is 5xpi square meters. Thus the area 6 diameter circle exceeds the combined area by (9-5)xpi= 4xpi square meters. Substituting the value of pi as 3. 14, the exceeding area is 12. 56 square meters.
calculate the area of both circles and then subtract the smaller area from the larger area you have your gap.
