Line l : x + y = 4 intersects the circle x^2 + y^2 - 2x - 2y = 2 at points A and B . If C is the center of the circle, then the area of ABC is...
Options
- A2
- B2
- C2 2
- D4
Correct answer
B. 2
Step-by-step solution
Equation of the circle is x^2 + y^2 - 2x - 2y = 2 , which can be written as (x-1)^2 + (y-1)^2 = 4 . Center of the circle is C(1, 1) and radius is R = 2 . The perpendicular distance d from the center C(1, 1) to the line x + y - 4 = 0 is given by d = |1 + 1 - 4| 1^2 + 1^2 = 2 . The length of the chord AB is 2 R^2 - d^2 = 2 2^2 - ( 2 )^2 = 2 2 . The area of ABC is 1 2 AB d = 1 2 2 2 2 = 2 . Answer: 2
