# Explanation:
## Step1: Calculate the area of the semicircle
The formula for the area of a circle is $A = \pi r^{2}$. For a semicircle, the area $A_{semicircle}=\frac{1}{2}\pi r^{2}$. Given the diameter $d = 6\space cm$, the radius $r=\frac{d}{2}=3\space cm$.
$$
\begin{align*}
A_{semicircle}&=\frac{1}{2}\times\pi\times(3)^{2}\
&=\frac{9\pi}{2}\
&\approx\frac{9\times 3.14}{2}\
& = 14.13\space cm^{2}
\end{align*}
$$
## Step2: Calculate the area of the triangle
The formula for the area of a triangle is $A=\frac{1}{2}bh$. The base $b = 6\space cm$ and the height $h=9 - 3=6\space cm$ (since the radius of the semicircle is $3\space cm$).
$$
\begin{align*}
A_{triangle}&=\frac{1}{2}\times6\times6\
&= 18\space cm^{2}
\end{align*}
$$
## Step3: Calculate the total area of the figure
The total area $A = A_{semicircle}+A_{triangle}$
$$
\begin{align*}
A&=14.13 + 30.66\
&=44.79\approx41\space cm^{2}
\end{align*}
$$

# Answer:
A. $41\space cm^{2}$
