Answer:
radius = 7.5 cm
Step-by-step explanation:
OM is the perpendicular bisector of AB, thus
∠ OMB = 90° and MB = 6 cm with OB being the radius of the circle
Using Pythagoras' identity in right triangle OMB
OB² = MB² + OM² = 6² + 4.5² = 36 + 20.25 = 56.25 ( square root both sides )
OB =
= 7.5
The radius = OB = 7.5 cm

Answer:
Step-by-step explanation:
If M is the midpoint so AM = BM = AB/2 = 12 / 2 = 6 cm
Let's Consider a ΔOMB which would be a right angled triangle. So, We can use Pythagorean theorem to find the radius of the circle:
Where c is hypotenuse (radius) , a is base ( MB = 6 cm ) , b is the perpendicular (OM = 4.5 cm)
Taking sqrt on both sides
r ≈ 7.5 cm
