Answer:
C) 75
Step-by-step explanation:
I got this because what you have to do, they all have to add up to 180. so what you do is:
2x + 30 = 180
-30 -30
2x = 150
2x/2 = 150/2
x = 75

The formula you use is
V = (4/3)*pi*r^3
In this case, r = 6 is the radius, so the volume V is
V = (4/3)*pi*r^3
V = (4/3)*pi*6^3
V = (4/3)*pi*216
V = (4/3)*216*pi
V = 288pi
