Circles are congruent when they have the same radius and they are similar when their radii are different in lengths.

2 circles can be congruent. The have to have the same radius.

They are all circles. The vertical and horizontal have the same radius as the ball while the angled cross section has a smaller radius.

The center of a circle is the same for all circles but the length of the radius can change

Circles with the same radius are congruent circles.

Concentric circles are the circles with the same center therefore they do not cross with each other as the "center is not considered a point on the circle". An exception would be two circles that are concentric and have the same radius, in which case the circles are indistinct and every point of the circles is an intersection.

If you create third circle with radius 2, then all the points on that circle would be equidistant form both circles. So the answer is a circle with radius 2.

Circles are congruent when they have the same radius and they are similar when their radii are different in lengths.

the radius is from the center of the circle to the edge so that's how you find the radius.

The question is misguided. You do not use radius only on circles!

By using Cartesian equations for circles on the Cartesian plane

area of the circle is half the product of its circumference and radius by coiling method (for 10 circles of different radius).
