82.5 / 5.5 = 15
15 hrs.
i think that should be the answer but i didn't use the 2.3 -meter-thick clue...
Remember that transformation between Cartesian and polar system are:
x=r*cos(α)
y=r*sin(α)
From this we can conclude that:
r=√(x^2 + y^2)
Using trigonometry transformations we can write:
r=sin(2α) = 2sin(α)cos(α)
Now we can multiply both sides with r^2:
r^3 = 2(r*sin(α))*(r*cos(α))
Now using some replacements we can write:
(x^2 + y^2)^(3/2) = 2*x*y
1 7/24 is the correct answer I will show you how to get it if needed.
24*7 = 168
(2*12)*7=168
168*2=336
