Answer:

(B)
$7{\pi}cm$

Explanation:

We are given the radius of the circle that is equal to
3(1)/(2)cm .

Now, circumference of circle is given as:

$C=2{\pi}r$

$C=2{\pi}(3(1)/(2))$

$C=2{\pi}((7)/(2))$

$C=7{\pi}cm$

Therefore, the circumference of the circle is
$7{\pi}cm$ .

Hence, option B is correct.
