Question

question 10 of 10 the blue segment below is a diameter of ⊙o. what is the length of the radius of the circle? a. 3.7 units b. 11.1 units c. 7.4 units d. 14.8 units

Explanation:

Step1: Recall radius - diameter relation

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

Step2: Identify diameter value

The diameter $d = 7.4$ units as given in the problem.

Step3: Calculate radius

Substitute $d = 7.4$ into the formula $r=\frac{d}{2}$, so $r=\frac{7.4}{2}=3.7$ units.

Answer:

A. 3.7 units
