1. The radius of any other congruent circle will be the same  that is 3.5 cm since the diameter of the other circle is 7 cm.

2. If two circles are not congruent , then the angles subtended by chords of equal lengths at the respective centres are (a) equal because though the circles are not congruent but every circle is similar to each other.

3. The angle subtended by the diameter of a circle at it's centre is 180° since the diameter divides the circle into two equal halves and the total angle at a point is 360°.
