Answer: A=351.68 cm²

Step-by-step explanation:

To find the area of the shaded region, we would subtract the area of the circle by the area of the inner circle.

Area of Circle

$A=\pi r^2$

$A=\pi (11)^2$

$A=121\pi$

Area of inner (white) circle

$A=\pi r^2$

$A=\pi (3)^2$

$A=9\pi$

Now that we have the area to the circle and inner circle, we would subtract to find the area of the shaded region.

$A=121\pi -9\pi$

$A=112\pi$

$A=351.68 cm^2$

aalyn [17]

Answer:the number of 2 legged animals in the zoo is 9

the number of 4 legged animals in the zoo is 7

Step-by-step explanation:

Let x represent the number of 2 legged animals in the zoo.

Let y represent the number of 4 legged animals in the zoo.

There a 46 legs in the exhibit in the zoo. This means that

2x + 4y = 46 - - - - - - - - - -1

There are 2 more 2 legged animals than 4 legged animals. This means that

x - 2 = y

Substituting y = x - 2 into equation 1, it becomes

2x + 4(x - 2) = 46

2x + 4x - 8 = 46

6x = 54

x = 54/6 = 9

Substituting x = 9 into x - 2 = y, it becomes

y = 9 - 2 = 7
