Answer:
Volume = 200.96 cubic feet
Step-by-step explanation:
Volume of a cone is given by the formula 
Where r is the radius and h is the height
Given r = 4 and height is 3 times that. So height is 4*3 = 12
Plugging these into the formula we get:
Volume of Cone = 
Thus, Volume = 200.96 cubic feet
Answer:
x=10
Step-by-step explanation:
110 and 8x + 30 are vertical angles, which means they are equal
110 = 8x+30
Subtract 30 from each side
110-30 = 8x+30 -30
80 = 8x
Divide each side by 8
80/8 = 8x/8
10 =x
