Question

Does the point (-4,2 )lies inside or outside or on the circle (X ^2+Y^2=25)?

Answer 1

Answer:

Step-by-step explanation:

Concept :- at point (x1, y1) , if S1 > 0 then point lies outside . If S1=0 then point lies on the circle, and if S1 < 0 then point lies inside the circle. So, the point (-2.5, 3.5) lies inside the circle.
