$\Large \underline{\tt Given} :$

$\\$

$\Large \underline{\tt To \: Find} :$

$\\$

$\Large \underline{\tt Solution} :$

As, we have diameter of circle is 5.6 cm and radius is half of diameter.

$\tt : \implies Radius, r = (d)/(2)$

$\tt : \implies Radius, r = (5.6 \: cm)/(2)$

$\tt : \implies Radius, r = \frac{\cancel{56} \: cm}{10* \cancel{2}}$

$\tt : \implies Radius, r = (28 \: cm)/(10)$

$\tt : \implies Radius, r = 2.8 \: cm$

$\\$

Now, for Circumference :

$\Large \underline{\boxed{\bf{Circumference = 2\pi r}}}$

$\tt : \implies Circumference = 2 * (22)/(7) * 2.8 \: cm$

$\tt : \implies Circumference = \frac{44}{\cancel{7}} * \frac{\cancel{28}}{10} \: cm$

$\tt : \implies Circumference = 44 * (4)/(10) \: cm$

$\tt : \implies Circumference = (176)/(10)\: cm$

$\tt : \implies Circumference = 17.6\: cm$

$\\$

Hence, circumference is 17.6 cm.
