Answer:

<h2>10 inches</h2>

Step-by-step explanation:

Given the circumference= 30 in

we know that the formula for circumference is

$C= 2\pi r$

$30= 2*3.142*r\\\\r= \frac{30}{2*3.142} \\\r= \frac{30}{6.248}\\\r= 4.77 in$

The diameter is 2*r= 4.77*2=9.55 in

Approximately the diameter is 10 inches
