AP EAMCET · Maths · Circle
The centre and radius of the circle respectively are
- A
- B
- C
- D
Answer & Solution
Correct Answer
(A)
Step-by-step Solution
Detailed explanation
Given that: x2+y2+8x+10y-8=0 As we know that x2+y2+2gx+2fy+c=0 has centre -g,-f and r=g2+f2-c here, g=4, f=5, c=-8 centre ≡-4,-5, radius = r = 16+25+8=7
