A 4 cm x 6 cm rectangle sits inside a circle with radius with 11 cm. What is the area of the shaded region?
Novosadov [1.4K]

Answer:

The area of the shaded region is (121\pi -24)\ 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 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
