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
I believe it is 64 because 8 times 8 is 64
-20+15+30+-45=-20
-20/4=-5
The average is -5
Answer: The length of the second arc is 12 feet.
Step-by-step explanation:
Since we know that
A rope is swinging in such a way that the length of the arc is decreasing geometrically,
Length of first arc = 18 feet
Length of third arc = 8 feet
Let the length of second arc be x
As we know that
Hence, the length of the second arc is 12 feet.
Answer:
D. 0.098
Step-by-step explanation:
The probabilities of all choices must total 1, so we have ...
p(never) + p(married) + p(widowed) + p(divorced) = 1
p(divorced) = 1 - (p(never) + p(married) + p(widowed))
= 1 - (0.239 + 0.595 + 0.068) = 1 - 0.902
p(divorced) = 0.098
