Answer:
28.26
Step-by-step explanation:
so your formula would be
C=πd
your subsition would be
c=3.14*9
so your finally answer would be
28.26
Hello!
To find a length, we want to find how many radians our arc length is. Let's convert our 73 degree angle into radians, which will give us our radian length.
(73)≈1.2741
Now, we know our arc length is equal to about 1.2741 radians. Let's multiply this by our radius.
1.2741(6.48)≈8.3
Therefore, our arc length is about 8.3 inches.
I hope this helps!

The mean time it takes to walk to the bus stop is 8 minutes (with a standard deviation of 2 minutes) and the mean time it takes for the bus to get to school is 20 minutes (with a standard deviation of 4 minutes). The distributions are normal.
a. How long will it take (in minutes), on average, to get to school?
b. What is the standard deviation of the trip to school?
c. What is the probability that it will take longer than 30 minutes to get to school?
Due to a miscalculation, you realize it actually takes an average of 10 minutes to walk to the bus stop.
d. How long will it take (in minutes), on average, to get to school?
e. What is the standard deviation of the trip to school?
f. What is the probability that it will take longer than 30 minutes to get to school?
The only ones I need help with is C and F. I have the answer for the rest of them. Can someone please help me with parts C and F??
You need to make the same denominator for last fraction
