   First of all we will find the radius

   [tex]\implies[/tex] [tex]2 ÷ 10[/tex]

   [tex]\implies[/tex] [tex]5[/tex]

   So the radius = 5 cm

   Now we will find the perimeter/circumference

   [tex]\implies[/tex] [tex]Perimeter \: of \: semicircle \: = [tex]\frac{perimeter \: of \: a \: circle}{2}[/tex] + 10

   [tex]\implies[/tex] [tex]5 × 3.14 × 10[/tex]

   [tex]\implies[/tex] [tex]15.70 + 10[/tex]

   [tex]\implies[/tex] [tex]25.70cm[/tex]

   [tex]\implies[/tex] [tex]Therefore \: the \: perimeter \: = \: 25.70cm[/tex]
