Question

question 7 of 10
the blue segment below is a diameter of o. what is the length of the radius of the circle?
a. 7.7 units
b. 3.85 units
c. 11.55 units
d. 15.4 units

Explanation:

Step1: Recall the relationship between radius and diameter

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

Step2: Substitute the given diameter value

Given \(d = 7.7\) units. Then \(r=\frac{7.7}{2}=3.85\) units.

Answer:

B. 3.85 units
