Question

question 3 of 10 the blue segment below is a diameter of ⊙o. what is the length of the radius of the circle? a. 10.35 units b. 6.9 units c. 3.45 units d. 13.8 units

Explanation:

Step1: Recall radius - diameter relation

The radius $r$ of a circle is half of its diameter $d$, i.e., $r=\frac{d}{2}$.

Step2: Identify diameter value

The diameter $d = 6.9$ units.

Step3: Calculate radius

$r=\frac{6.9}{2}=3.45$ units.

Answer:

C. 3.45 units
