There’s no value of x that make the equation true. (No solution)
Answer:

Step-by-step explanation:
The formula of a volume of a sphere:

R - radius
We have R = 3 ?. Substitute

If the radius is 30, then the volume is:

If 30 is the length of diameter, then the radius R = 30 : 2 = 15.
Therefore the volume:
