r=8~cm

Step-by-step explanation:

Greetings!

I'm~Isabelle~Williams~and~I~will~be~answering~your~question!

To~find~the~radius~of~a~circle~we~have~to~use~the~formula~that~is:

$\boxed{~d=2r~}$

Now,~according~to~the~formula~we~divide~16~by~2:

$r=\frac{16}{2}=8~cm$

Thus,~the~radius~of~the~diameter~is~8~cm.

Hope~my~answer~helps!~Have~an~amazing~day~ahead!
