x=-2
Therefore, the answer is B. 1 and -2
Answer:
The answer is 256 .
Step-by-step explanation:
To solve for the volume of the sphere, start by using the sphere volume formula, which is V = . However, in this formula, 3 will be used instead of ().
Next, plug in the information given from the problem, and the formula will look like V = (3) ().
Then, solve the equation, and the answer will be 256 .
