Respuesta :
OC is the perpendicular bisector pf line AB
So, length of AB will be
3.6x2=7.2
ANSWER: b) 7.2
So, length of AB will be
3.6x2=7.2
ANSWER: b) 7.2
Chord AB is perpendicular to CO joining the center. Thus, AB = 7.2 units.
What is a chord?
The chord is a line segment that joins two points on the circumference of the circle. A chord only covers the part inside the circle.
The perpendicular from the center of a circle to a chord bisects the chord.
Thus, CO bisects AB at C.
This implies that, AC = CB.
AB = AC + CB
AB = 2AC
AB = 2 * 3.6 = 7.2 units
