Answer:
105
Step-by-step explanation:
This means that...
the first worker does 1/8 of the job each hour.
the second worker does 1/4 of the job each hour.
the third worker does 1/4 of the job each hour.
So together they get 1/8+1/4+1/4 of the job done per hour.
Rate: 5/8 of the job per hour
Now if we know the rate, the job will be finished in...
1/(5/8) hours ----> 1.6 hours or 1 hour and 36 minutes
answer: 1.6 hours or 1 hour and 36 minutes
A = pi r^2
A = 3.14 x (5.5)^2
A = 94.985
