Question

unsure about this one tried and couldn’t seem to figure it out

Answer 1

Given:

The figure contains the rectangle and half-circle.

The perimeter of the half-circle is,

$\begin{gathered} \text{Half}-\text{circle}=\pi r+d \\ r=\frac{d}{2}=\frac{8}{2}=4 \\ \text{Half}-\text{circle}=\pi(4)+8 \\ =3.14\times4+8 \\ =20.56 \end{gathered}$

The perimeter of the figure is,

$P=10+8+10+20.56=48.56$

Answer: P = 48.56 ft.
