AP EAMCET · Maths · Circle
If the power of the point with respect to the circle is then equals
- A
- B
- C
- D
Answer & Solution
Correct Answer
(C)
Step-by-step Solution
Detailed explanation
As we know, power of a point x1,y1 w.r.t. the circle is x12+y12+2gx1+2fy1+C So, Power of point 1,6=12+62+4×1-6×6-a ⇒-16=5-a ⇒a=21
