Question

Here is a circle with center A. The length of segment BA is 12 cm.
What is the length of segment DA?

Answer 1

Answer:

• AD = 12 cm

-------------------------

Point A is the center and both A and D are on the circle.

As per definition, the length between the center and any point on the circle is its radius.

Therefore both AB and AD have same length of 12 cm as radius.
