Answer:

The radius of circle O is 8.5 Units

Step-by-step explanation:

Solution

The radius of a circle is refereed to as the  half of the diameter.

Now,

On how to figure out the length of AB, we apply the  Pythagorean's equation or formula which is given below

Thus,

a² + b² = c²

(15)² + (8)² = c²

225 + 64 = c²

√289 = √c²

Then

c = 17

What this shows is that  AB is 17 units.

Since we have gotten the diameter, the next step is to divide into half the know the radius value

Therefore,

17 ÷ 2 = 8.5 Units

= 8.5 Units.
