here we have:

Answer 3

3.14 x (semi circle)?

Answer 4

no, it says add

Answer 5

my first thought was 3.14 x 8 but that's probably not it

Answer 6

the requested perimeter is equal to this sum:
\[\begin{gathered}
{\text{sum of the length of linear segments + }} \hfill \\
{\text{ + length of half circle}} = \hfill \\
= 7 + 16 + 7 + \left( {3.14 \times 8} \right) \hfill \\
\end{gathered} \]

Answer 7

i got 265.12

Answer 8

hint:
\[\begin{gathered}
{\text{sum of the length of linear segments + }} \hfill \\
{\text{ + length of half circle}} = \hfill \\
= 7 + 16 + 7 + \left( {3.14 \times 8} \right) = \hfill \\
= 16 + 14 + 25.12 = ... \hfill \\
\end{gathered} \]
