Answer 1

Answer :-

Perimeter of Semicircle = 36 cm²

Explanation :-

Given :

• Radius of Semicircle = 7 cm.

To Find :

• Perimeter of Semi Circle.

Solution :

Formula Used :-

$\bigstar \:{\boxed{\sf{Perimeter \: of \: Semi \: Circle = r(\pi + 2)}}}$

So, Let's Solve.

Note :- Here, I am taking value of π as 22/7.

$\implies\sf{Perimeter = 7\bigg(\dfrac{22}{7} + 2\bigg)}$

$\implies\sf{Perimeter = 7 \times \dfrac{22}{7} +7 \times 2}$

$\implies\sf{Perimeter = 22 +14}$

$\implies\underline{\boxed{\sf\red{Perimeter = 36 {cm}^{2} }}}$

∴ Perimeter of Semicircle = 36 cm²
