The area (in square unit) of the circle which touches the lines 4 x+3 y=15 and 4 x+3 y=5 is

Options

  1. A4
  2. B3
  3. C2

Correct answer

3

Step-by-step solution

Since, given lines are parallel. aligned & d= 15-5 4^2+3^2 = 10 5 & d=2= diameter of the circle & Radius of circle =1 & Area of circle = r^2= sq unit aligned
