Answer:
> Your question is vague or incomplete because there is no figure. However, there's the measure of diameter so you can easily get the measure of its radius.
> Just divide the diameter by two, the result is the radius.
> Radius is one-half of diameter.
[tex]Radius= \frac{1}{2} \: Diameter \\ Radius= \frac{1}{2} (15) \\ Radius= \frac{15}{2} \\ Radius=7.5[/tex]
