MQ 2 Find the center and Radius of the circle ײ+y²-4×-8y-41=0
​

Answer 1

Answer:

centre is (2,4) and radius is ✓(61)

Step-by-step explanation:

where 2g =-4 and 2f = -8 and centre of circle is (-g,-f) ..

therefore, centre of circle is (2,4) ......

and radius of circle formula is

$\sqrt{g ^{2} + f ^{2} - c}$

where g= -2 and f= -4 and c= -41 by substitution we get ✓(61)
