Yes, it is true. Any circles with the same radius will have the same circumference as well.
No, it's not true that all circles with a radius of 0 cm have circumferences of the same length because a circle with a radius of 0 cm is actually just a point. A point does not have a circumference, as circumference is defined for circles with a positive radius. Therefore, circles with a radius of 0 cm do not exist in the traditional sense of geometry.
The center of a circle is the same for all circles but the length of the radius can change
The bases of a cylinder are circles and both have circumferences Area of the base of cylinder and a circle is pi*radius2 Circumference of a cylinder and a circle is 2*pi*radius or diameter*pi
The converse of the statement "If two circles have the same diameter, then they have the same circumference" is "If two circles have the same circumference, then they have the same diameter." This means that if you know two circles share identical circumferences, you can conclude that their diameters are also equal.
They are congruent or identical circles

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

congruent circles
The same radius.
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.
congruent
No. Concentric circles have the same centre but not [usually] the same radius. Congruent circles have the same radius, but not [usually] the same centre. If you have two concentric congruent circles one will be exactly on top of the other.
They are congruent or identical circles
