**Sphere and Paraboloid** A sphere of radius 4 is dropped into the paraboloid given by

(a) How close will the sphere conic to the vertex of the paraboloid?

(b) What is the radius of the largest sphere that will touch the vertex?

Expert Solution

**(a)**

To determine

**To Calculate:** The closeness of the sphere of radius 4 to the vertex of the paraboloid

**Given:**

A paraboloid,

**Formula Used:**

The derivative of a function

**Calculation:**

Assume a circle,

Now, the circle will drop to the point where the tangents to the circle and parabola are equal.

Consider,

Next, the derivative of the above equations with respect to

Expert Solution

**(b)**

To determine

**To Calculate:** The radius of the largest sphere that will touch the vertex of the paraboloid
