Answer:
52pi
Step-by-step explanation:
You need the area of the large grey circle, minus the white circle, plus the small grey
Large grey = 8^2 * pi = 64pi
White = 4^2 * pi = 16pi
Small grey = 2^2 * pi = 4pi
64pi - 16pi = 48pi, 48pi + 4pi = 52pi
Step-by-step explanation:
This is the values needed
Answer:
D
Step-by-step explanation:
2 x 2 = 4 x PI = 12.56
I gram = 0.00220462 pounds
so 14000 x 0.00220462 = 30.864717
round off answer as needed
I think the answer is 5, if you divide 7.5 by 1.45 you get 5.2 or 5.17 so approximately 5.
