Answer:
x= 14.8 -16.83
Step-by-step explanation:
Try to get x by itself
6x= 89-101
divide both sides by 6 and you get x= 14.8 -16.83
The volume of a cone is
V = (1/3) π r² h
where r = radius of the base
h = the height.
The volume of the frustum is
(1/3)π(7.5²)(11+8) - (1/3)π(3.5²)(8)
=(1/3)π(7.5²)(19) - (1/3)π(3.5²)(8)
The 3rd choice is the correct answer.
