Answer:
7.5 pi
Step-by-step explanation:
The formula for arc length of a sector is denoted as
, where x is the central angle of the sector.
Since the sector is 3/4 of a circle, the central angle will be 3/4 of 360 degrees.
3/4 of 360 is 270, so we have our central angle. We also have our radius which we can plug into the formula.
2 times 5 is equal to 10, and 270/360 simplifies to 3/4. 3/4 times 10 is equal to 7.5, so the answer is 7.5 pi
Answer:
P (Even number) = 1/2
P(spinner will land on an odd number) = 1/2
P(spinner will not land on 2 or 3) = 3/4
P(spinner will not land on a multiple of 3) = 3/4
Step-by-step explanation:
Here, while spinning the spinner total possible outcomes
are 8 = {1,2,3,4,5,6,7,8}
Now,
a) E: Probability of getting even number
Favorable outcomes are {2,4,6,8}
Hence,
b)E: Probability that the spinner will land on an odd number.
Favorable outcomes are {1,3,5,7}
Hence,
c) E: Probability that the spinner will not land on 2 or 3
Favorable outcomes are {1, 4,5,6,7,8}
Hence,
d) E: Probability that the spinner will not land on a multiple of 3
Favorable outcomes are {1,2,4,5,7,8}
Hence,
