The shortest distance from the plane 12 x+4 y+3 z=327 to the sphere x^2+y^2+z^2+4 x-2 y-6 z=155 is

Options

  1. A39
  2. B26
  3. C11 4 13
  4. D13

Correct answer

D. 13

Step-by-step solution

Shortest distance = perpendicular distance = | -2 12+4 1+3 3-327 144+9+16 |=26 Shortest distance =26- 4+1+15+9 =26-13=13 [ 26-r]
