### Equation of Sphere Given Tangent Plane 1

Multivariable Calculus: Find the equation of the sphere with center (-4, 2, 3) and tangent to the plane 2x-y-2z + 7 = 0. In Part 1, we use vector analysis to find the radius. (In Part 2, we minimize the distance function by finding a critical point; in Part 3, we use Lagrange multipliers.)
