Question

question 2 of 10 the blue segment below is a radius of ⊙o. what is the length of the diameter of the circle? a. 9.8 units b. 14.7 units c. 19.6 units d. 4.9 units

Explanation:

Step1: Recall diameter - radius relation

The diameter $d$ of a circle is related to the radius $r$ by the formula $d = 2r$.

Step2: Substitute given radius value

Given $r=9.8$ units, then $d = 2\times9.8$.
$d=19.6$ units

Answer:

C. 19.6 units
