Find the center and radius of the following sphere: x^2 + y^2 + z^2 - 8y = 0
Added by Bridget G.
Step 1
To do this, we can complete the square for the y term. We have: x^2 + y^2 - 8y + z^2 = 0 Now, we need to add and subtract the square of half the coefficient of the y term, which is (-8/2)^2 = 16. So, we get: Show more…
