nirvana33 [79]

Answer:

The answer is C. 904.32 in^3.

Step-by-step explanation:

To find the volume of a sphere with a radius of 6 in, start by using the formula for a sphere, which is V= $\frac{4}{3}$ $\pi$ $r^{3}$ . However, for this formula instead of using ( $\pi$ ), 3.14 will be used.

Now, plug the radius into the formula, and solve for V.

Finally, the answer will be 904.32 in^3.
