360 degrees is the whole circumference.
300 degrees is 300/360 of the circumference.
The circumference: pi*r*2 = 4*pi = approximately 12.566.
300/360*12.566=10.472 = answer

Step-by-step explanation:
Answer:
170 students liked reading mystery stories.
Step-by-step explanation:
In order to find this, we first must find the total number of students. We can do this by dividing the number who did not like reading mystery stories (30 student) by the percentage of the overall that it represents (15%)
30/.15 = 200 students
Now that we know how many students there are, we can multiply that by the percentage who like mystery stories to get the number.
200 students * .85 = 170 students
Answer:
Hence, the probability of selection of one new rock song is 
.
Step-by-step explanation:
As given in the question, Doug bought 9 new country songs and 5 new rock songs.
and we have to find the probability that it will be a rock song.
Now,
Doug bought 9 new country songs
Doug bought 5 new rock songs
Therefore, Total number of songs bought by Doug = 9 new country songs + 5 new rock songs
∴ Total number of songs bought by Doug = 5+9 = 14.
∵ 
Let, the event A is defined as the selection of one Rock Song
∴
Hence, the probability of selection of one new rock song is .
V = ( 9*2 ) / 3 ;
v = 18 / 3 ;
v = 6 ;
a. is the right answer;
( 119.5 / 151 ) * 100 = 11950 / 151 = 79.1 ;
The percent is 79.1%;
c. is the right answer;
1 - (40/100)*1 = 1 - 2 / 5 = 3 / 5 = 0.60 ;
d. is the right answer.
