Question

question 7 of 10
the blue segment below is a radius of $odot o$. what is the length of the diameter of the circle?
a. 21.2 units
b. 10.6 units
c. 5.3 units
d. 15.9 units

Explanation:

Step1: Recall the radius - diameter relationship

The diameter $d$ of a circle is twice the radius $r$, i.e., $d = 2r$.

Step2: Identify the radius value

The radius $r=10.6$ units.

Step3: Calculate the diameter

Substitute $r = 10.6$ into the formula $d = 2r$, so $d=2\times10.6 = 21.2$ units.

Answer:

A. 21.2 units
