Given:

The perimeter of the semicircle is P = 35.98.

To find the radius of the semicircle:

Step-by-step explanation:

Using the formula of the perimeter of the semicircle,


\begin{gathered} P=(\pi+2)r \\ 35.98=(3.14+2)r \\ 35.98=(5.14)r \\ r=(35.98)/(5.14) \\ r=7 \end{gathered}

Hence, the radius of the semicircle is 7.
