V= pi r^2=3.14*r^2
our V=14,542 m^3
14,524=3.14*r^2 divide both sides by 3.14
4625.47=r^2
r =
r=68
avg. service time = 2hrs +/- 32 mins = 180 mins +/- 32 mins = 148 mins or 212 mins.

Seriously I dont know the answer to the problem, but it is an interesting question, and it forces me to study probability more.
Answer:
x = 34
Step-by-step explanation:
This is a right angle. This means that the square to the bottom right is 90 degrees. There is also an angle that is 124, but that is a linear pair to the angle on the inside. This means that 124+__=180 degrees
180-124= 56
So now we know 2 angles, which are 90 degrees and 56 degrees. Because we know that the sum of the angles of a triangle equal 180 degrees, we can subtract 90 and 56 from 180 to get our answer, 34.

(1/3) + (1/2)
=> [(1×2)/(3×2)] + [(1×3)/(2×3)]
=> (2/6) + (3/6)
=> (5/6)
