Question

use the provided dimensions to find the radius.
multiple choice question
whats the diameter of the circle?
60.24 cm?
19 cm?
4 cm?
(image of a circle with a diameter labeled, and some text about using dimensions to find radius)

Explanation:

Step1: Recall radius-diameter relation

The diameter $d$ of a circle is twice the radius $r$, so $d = 2r$. From the diagram, the radius $r = \frac{8}{2} = 4$ cm.

Step2: Calculate the diameter

Substitute $r=4$ into the formula.
$d = 2 \times 4$

Answer:

D. 8 cm
