the answer is -3/2 and -11/2
I'm guessing you are looking for the answer on the first question, because I cannot read the rest of the second one lol.
So start with the volume of cone formula: V=3.14(5)^2 (6/3)
157.08
157
H is the answer
1) the sum of all three angles in a triangle is always 180, so number 5 is w=80
2)I assume they mean x. since the x angle and the 70 angle are a linear pair they must add to 180, so x has to be 110
3) the top 60 angle makes a vertical angles with the angle right below it. since vertical angles are congruent, the angle below has to be 60 also. again all 3 must add to 180 so o is also 60
4) these are all linear pairs. every angle shown has to be 90
Answer:

Step-by-step explanation:
60 · 60 · 60
60³ = 180
Diameter - 8
3 sides, diameter 8 = answer.
