You maybe thinking of a 3D cylinder whose 2D net would fit the given description
Tangent circles are circles that touch one another without crossing. The distance between the centres of the circles must be equal to the difference or the sum of their radii.
Assume that the two inscribed circles are "side-by-side" and have the same radii of r, then: A= 8 x r x r.
They are congruent circles
Are congruent circles.
They are congruent or identical circles
Yes
True providing that they have the same diameters
Tangent circles are circles that touch one another without crossing. The distance between the centres of the circles must be equal to the difference or the sum of their radii.
Yes. Congruent circles by definition have the same size, and the radius sufficiently describes the size of a circle.
Yes, that is correct. Circles circumscribed about a given triangle will have centers that are equal to the incenter, which is the point where the angle bisectors of the triangle intersect. However, the radii of these circles can vary depending on the triangle's size and shape.

False
If they're in the same circle or in circles of equal radii (radiuses), then yes.
