Answer: 397.39 cm2
Step-by-step explanation:
Hi, first we have to calculate the area of the circle:
Area of a circle = π x r^2
Replacing with the values:
A(C) =π x 12^2 = 452.39cm2
Now, we have to calculate the rectangle area:
Rectangle area = width x length = 5 x11 = 55cm2
Finally, since the shaded region is the circle and the rectangle is inside of it, we have to subtract the area of the rectangle to the area of the circle:
452.39 -55 = 397.39 cm2
