$\large\bf{\underline\red{Good \: Afternoon♡}}$

Given diameter of circle = 4cm

Radius = 4/2

= 2cm

The perimeter of quadrant of circle = $( \frac{\pi}{2} + 2)r$

= $( \frac{22}{7 \times 2} + 2)2$

= $( \frac{22}{14} + 2)2$

= $( \frac{11}{7} + 2)2$

= $( \frac{11 + 14}{7} )2$

= $( \frac{25}{7} )2$

= $\frac{50}{7}$
