Question

A circle with radius of 1cm sits inside 3cm x 3cm rectangle

Answer 1

Answer:

The area of the shaded region is 5.86\ cm^{2}

Step-by-step explanation:

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

The rectangle is a square

so

A=b^{2} -\pi r^{2}

we have

b=3\ cm

r=1\ cm

assume

\pi =3.14

substitute the values

A=3^{2} -(3.14)(1)^{2}

A=5.86\ cm^{2}
