Answer:

23 inches

Step-by-step explanation:

Diameter:
$d=(C)/(\pi)$

$d=(C)/(\pi) \\\\d=(72)/(3.14) \\\\d=22.929\\\\d=23$

Check your answer using the circumference of a circle:
$C=2*\pi*r$

Radius (r) = d/2. So 23/2 = 11.5

$C=2*\pi*r\\\\C=2*3.14*11.5\\\\C=72.22\\\\C=72\ inches$

Hope this helps!
