Answer:

The area of the shaded region is
$(121\pi -24)\ cm^(2)$

Explanation:

we know that

The area of the shaded region is equal to the area of the circle minus the area of the rectangle

so

$A=\pi r^(2) -bh$

we have

$r=11\ cm$

$b=4\ cm$

$h=6\ cm$

substitute the values

$A=\pi (11^(2)) -(4)(6)$

$A=(121\pi -24)\ cm^(2)$ ----> exact value of the shaded area
