Answer 2

The Required Answer is as follows ;

$\textrm{Circumference of Circle = 2 \pi r}$

$\implies\textrm{Circumference of Circle = 2 \times\:\pi\:\times r}$

$\implies\textrm{Circumference of Circle = 2 \times 22/7 \times 28 cm }$

$\implies\textrm{Circumference of Circle = 2 \times 22 \times 4 cm }$

$\implies\textrm{Circumference of Circle = 176 cm }$
