Let R be the region of the disc x²+y² 1 in the first quadrant. Then the area of the largest possible circle contained in R is
Options
- A(3-2 2 )
- B(4-3 2 )
- C6
- D(2 2 -2)
Correct answer
A. (3-2 2 )
Step-by-step solution
Required equation of circle (x-h)²+(y-h)²=h² Both circle touch internally array l C ₁ C ₂= | r ₁- r ₂ | h ²+ h ² =| h -1| array Solve this h = 2 -1 Area ( 2 -1)²= (3-2 2 )
