Answer 2

Answer:

9.0 cm

Step-by-step explanation:

Since the diameter of the circle is two times of the radius because diameter is the largest chord of the circle and it passes through the centre of the circle so it's distance from the centre to the points lie on both sides of the circle will be always same.

So here radius is given to us is 4.5 cm

Diameter will be

2R = 2*4.5 = 9.0 cm
