Answer:
x=-4
Step-by-step explanation:
(x+4) ^ (1/3) + (2x+8) ^ (1/3) = 0
Subtract (x+4) ^ (1/3) from each side
(x+4) ^ (1/3) - (x+4) ^ (1/3)+ (2x+8) ^ (1/3) = -(x+4) ^ (1/3)
 (2x+8) ^ (1/3) = -(x+4) ^ (1/3)
Cube each side
 (2x+8) ^ (1/3) ^3= -(x+4) ^ (1/3)^3
2x+8 = -(x+4)
Distribute the negative sign
2x+8 = -x -4
Add x to each side
2x+8 +x =-x+x-4
3x+8 = -4
Subtract 8 from each side
3x+8-8 =-4-8
3x =-12
Divide by 3
3x/3 = -12/3
x = -4

Explanation:
Given:
radius of the cylinder = 4.5cm
height = 9cm
To get the volume of the cylinder, we will use the formula:


To the nearest hundredth, the volume of the cylinder is 572.27 cm³

Answer:
4 inches 
Step-by-step explanation:
The radius is the line from the center of the circle to the edge. We can assume the black line on the orange is the radius. 
We want to find the diameter. The diameter is twice the radius, or 
d=2r 
We know the radius is 2, so we can substitute that in for r 
d=2*2
Multiply 
d=4 
So, the diameter is 4 inches
