Answer 1

Answer:

Area of Large Circle = 380.13

Area of Small Circle = 254.47

Area of Sidewalk = 125.66

Step-by-step explanation:

The side walk is just subtracting the smaller number from the bigger one.

The area is just Pi*r^2

Answer 2

Answer:

A  379.94 m^2

B 254.34 m^2

C 125.6 m^2

Step-by-step explanation:

A  Area of a circle is given by

A = pi r^2

We know the radius is 11

A = pi 11^2

A = 3.14 (121)

A = 379.94 m^2

B The Area of the orange circle

A = pi r^2

The radius is 9 m

A = pi 9^2

A = 3.14 (81)

A = 254.34 m^2

C  The Area between the circles is the difference between the large circle and the small circle
