Question

question 8 of 10
the blue segment below is a radius of ⊙o. what is the length of the diameter of the circle?
a. 7.3 units
b. 3.65 units
c. 21.9 units
d. 14.6 units

Explanation:

Step1: Recall the relationship between radius and diameter

The formula for the diameter \(d\) of a circle in terms of the radius \(r\) is \(d = 2r\).

Step2: Substitute the given radius value

Given \(r=7.3\) units. Substitute \(r = 7.3\) into the formula \(d = 2r\), so \(d=2\times7.3\).

Step3: Calculate the diameter

\(2\times7.3 = 14.6\)

Answer:

D. 14.6 units
