Answer:

$C\text{ = }\pi r$

Step-by-step explanation:

Formula for calculating the circumference of a circle is expressed as;

$C\text{ = 2}\pi r$

r is the radius

Since a semi-circle is half of a circle, then the circumference will be half of cirumference of a circle as shown;

$\begin{gathered} C\text{ = }(2\pi r)/(2) \\ C\text{ = }\pi r \end{gathered}$

This gives the circumference of s semicircle where r is the radius of the semi circle
