Answer:
179.50
Step-by-step explanation:
The equation for volume of a cone is:
The radius is half of the diameter so r= 3.5 in
The height is 4 times the radius so h=14
V= 179.50

So the Level III editor does it in 15 hours, the Level II(slower) does it in 25 hours and the Level I(even slower), does it in 34 hours.
now, since the Level III one does it in 15 hours, in 1 hour alone, how much has it done? well, it only has done 1/15 of the whole work.
the Level II has 1 hour done only 1/25 of the whole work then, and the Level I has only done 1/34 of the whole work.
now, say they all do it in "t" hours, so how much have they edited in 1 hour altogether then? well, they have only done 1/t.

Let's remember some angle pair rules:
-> Co-Interior angles add up to 180º.
-> Alternating angles are equal.
-> Corresponding angles are equal.
-> Vertically opposite angles are equal.
-> Angles on a straight line add up to 180º.
-------------------------------------------------------------------------------------------------------------
Knowing that, and knowing Angle 6 = 102º, you can easily find any of the 7 angles.
I will skip angle 1 for now, you'll understand why.
Angle 2 and Angle 6 are Corresponding, so Angle 2 must be 102º.
Angle 3 is Vertically Opposite to Angle 2, so Angle 3 must be 102º.
Angle 4 is Co-Interior to Angle 6, so we calculate it this way:
Angle 4 must be 78º.
Angle 1 is Vertically Opposite to Angle 4, so it must be 78º.
Angle 5 is Alternating to Angle 4, so Angle 5 must be 78º.
Angle 7 and Angle 5 are On A Straight Line, so Angle 7 is calculated this way:
Angle 7 must be 102º.
Angle 8 is Vertically Opposite to Angle 5, so it must be 78º.

I wrote some parts in bold so you can refer to the rules I wrote above.
-------------------------------------------------------------------------------------------------------------
<u>In summary:</u>
Angles 1, 4, 5, and 8 = 78º
Angles 2, 3, 6 and 7 = 102º
