How do we calculate the radius of the ball ?

Answer:
11.5 (i think)
Step-by-step explanation:
23 is the diameter and half of the diameter is the radius so 23 divided by 2 is 11.5.
Answer:
Step-by-step explanation:
In the picture you have a diameter of d = 23 cm.
The diameter is twice the radius: d = 2r.
Therefore, r = d : 2 → r = 23 cm : 2 = 11.5 cm
