radius [R]:9inches

Now

difference in volume of sphere:

volume of sphere of having radius [r-R]

= $\frac{4}{3} πr³$ - $\frac{4}{3} πR³$

Im so lost what the answer is

Rainbow [258]

Answer:

Unfortunately, we can't do anything with 41 as it has no factors. Since $3\sqrt{41}$ is already simplified, try submitting that as your answer. If that doesn't work then try un-doing their steps and get rid of the 3:

$3\sqrt{41}$

$\sqrt{41(9)}$

$\sqrt{369}$

Hope this helps!
