Since 3 is replacting x, and there is an x in the problem, replace any instance of x with the number 3! So you would have 2(3)^2+4

Find the volume of this sphere.<br> Use 3 for T.<br> V~ [?]in3<br> V = Tr3<br> r=4in
timofeeve [1]

Answer:

The answer is 256 in^{3}.

Step-by-step explanation:

To solve for the volume of the sphere, start by using the sphere volume formula, which is V = \frac{4}{3}  \pi  r^{3}. However, in this formula, 3 will be used instead of    (\pi).

Next, plug in the information given from the problem, and the formula will look like V = \frac{4}{3} (3) (4 in^{3}).    

Then, solve the equation, and the answer will be 256 in^{3}.
