The volume is 32.4
get the circumference and divide by pi which is 3.1415926535897932384626
Let's let x = the number of workers making $75 per day
Then that would mean (60 - x) would be the number of workers who make $100 per day.
Now the average salary, which needs to be 80, can be found by adding all the salaries of the 60 workers and dividing by 60. The following equation can model this problem:
[75x + 100(60 - x)]/60 = 80 simplify the left side of the equation
(-25x + 6000)/60 = 80 multiply both sides by 60
-25x + 6000 = 4800 subtract 6000 from both sides
-25x = -1200 divide both sides by -25
x = 48 recall we set 'x' to equal the number of workers making $75 per day
And there you have it! Hope this helps..
