I have attached the diagram associated with this question.
Answer:
AB = 7.4 units
Explanation:
The perpendicular distance from the center of the circle to any chord in the circle bisects this chord.
In the given:
O is the center of the circle
AB is a chord in the circle
OC is perpendicular on AB
This means that:
OC bisects AB
AC = CB
We are given that:
AC = 3.6 units
Therefore:
AB = AC + CB
AB = 3.6 + 3.6
AB = 7.2 units
Hope this helps :)
