The area of a circle is 98.56 cm2.

Let the radius of the circle be r.
​Now,

Area $=98.56$

$\Rightarrow \pi r^{2}=98.56$

$\Rightarrow \frac{22}{7} \times r^{2}=98.56$

$\Rightarrow r=5.6$

Now,

Circumference $=2 \pi r=2 \times \frac{22}{7} \times 5.6=35.2 \mathrm{~cm}$

Hence, the circumference of the circle is 35.2 cm.
