You answer is 4.7ExplanationI assume that the shaded region is the area inside of rectangle and outside the circleso

The shaded region is equal to the area of rectangle minus the area of circlestep 1

Find the area of rectangle

The area of rectangle is equal to multiply the length by the widthA= (3)-(11)=33 cm^2tep 2

Find the area of the circle

The area of the circle is

A=\pi r^{2}

we have

r=3\ cm

\pi =3.14

substitute

A=(3.14)(3^{2})

A=28.26\ cm^{2}step 3

Find the area of the shaded region

33-28.26=4.74\ cm^{2}I hope this helps you and Please hit the braninslist answer thank You!
