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

Answer:

3 cm

Step-by-step explanation:

First, find the volume of the cone.

V = $\frac{1}{3}$ $\pi$ r²h

V = $\frac{1}{3}$ (3.14)(9)(12)

V = 113.04

This means the sphere is also 113.04

Use the formula V = $\frac{4}{3}$ $\pi$ r³

113.04 = $\frac{4}{3}$ (3.14)r³

113.04 = 4.19r³

26.98 = r³

3 ≈ r
