Question

A 4cm×6cm rectangle sits inside a circle with a radius of 11cm. what is the shaded region?

Answer 1

Answer:

The area of the shaded region is $355.94\ cm^{2}$

Step-by-step explanation:

we know that

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

so

$A=\pi r^{2}-bh$

we have

$r=11\ cm$

$b=4\ cm$

$h=6\ cm$

assume

$\pi =3.14$

substitute

$A=\pi (11^{2})-4*6=121 \pi-24=121*(3.14)-24=355.94\ cm^{2}$
