Hey, Manuel!
We can first subtract \(-8+y\) from both sides, to get \(\sqrt{y^2}-8+y-(-8+y)=4-(-8+y), \sqrt{y^2}=-y+12\). After that, we can square both sides, expand, and expand again, to get \(y^2=y^2-24y+144\) . Solve, to get \(y=6\)
That is correct, EP and GA! Good job, both of you!
Beautiful explanation, CPhill! I like it!
Using the forumla, 4/3 pi r^3, we have 4/3*3.14*216=904.32cm^3, so the third option.
