If one end of the diameter of is then the co-ordinates of the other end is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(B)
Step-by-step Solution
Detailed explanation
Given: The equation of the circle is x2+y2-2x-6y-15=0 ⇒x-12+y-32-25=0 So the centre of the circle is 1,3 and its radius is 5. We know that the centre is mid-point of the diameter. Also one end of the diameter is 4,1 and let other end be a,b. By mid point formula, 1=a+42…
