Question

question 3 of 10
the blue segment below is a radius of \\(\odot o\\). what is the length of the diameter of the circle?
9.3
a. 9.3 units
b. 4.65 units
c. 27.9 units
d. 18.6 units

Explanation:

Step1: Recall diameter-radius relation

The diameter $d$ of a circle is twice its radius $r$, so $d = 2r$.

Step2: Substitute radius value

Given $r = 9.3$ units, substitute into the formula:
$d = 2 \times 9.3$

Step3: Calculate the diameter

$d = 18.6$

Answer:

D. 18.6 units
