C=(1/4)*circumference
Area=pq+3.142r^2
60*3.142=pq+3.142p^2
q=((1/4)*2p*3.142)+2*3.142
q=1.571p+6.284
188.52=1.571p^2+6.284p+3.142p^2
188.52=4.713p^2+6.284p
188520=4713p^2+6284p

Answer:
330(D)
Step-by-step explanation:
So lets go over what we know:
#1: 44 out of 80 people think they have a average fitness level.
#2: 80 out of the 600 people in the school were surveyed.
Using what we know, lets try and find the answer.
So lets divide the total amount of people, by the amount of people that took the survey:
600/80
=
7.5
Ok, so now we know that we need to take 7.5 surveys to find out what all the students think of their fitness level.
Now lets take teh amount of people in a single survey, with average fitness(44), and multpliy it by how many surveys are needed for the whole school(7.5):
44*7.5
=
330
This is the amount of people in the whole school who think they have an average fitness level.
I hope this helps! :)
