Answer: 280.8
Step-by-step explanation:
I'm assuming the deck is the shaded area.
To find the area of the deck, find the area of the large circle and subtract the area of the small circle from it:
A of large circle: R = (4.2/2) + 1.7 = 3.8; area: 3.8^2 * pi is about 45.3.
A of small circle: r = 4.2/2 = 2.1; area: 2.1^2 * pi is about 13.8
Now, subtract:
45.3 - 13.8 = 31.5 meters squared

Answer:
0.16 bags
Step-by-step explanation:
Given that:
the floor of the rabbit's cage is 4 feet long and one bag of shaving covers 5² ft.
the floor of the rabbit's cage which is 4ft = 25 ft for one bag of wood shaving
