What is the area of the shaded region plzz help
Aneli [31]

Answer:

78.10 cm^2

Step-by-step explanation:

The area of the shaded region is the area of the rectangle subtracted from the area of the circle.

area of circle = (pi)r^2

area of rectangle = LW

shaded area = area of circle - area of rectangle

shaded area = (pi)r^2 - LW

shaded area = (pi)r^2 - LW

shaded area = (3.14159)(6 cm)^2 - (7 cm)(5 cm)

shaded area = (3.14159)(36 cm^) - 35 cm^2

shaded area = 113.097 cm^2  35 cm^2

shaded area = 78.097 cm^2

Answer: 78.10 cm^2
