Question

Does the point p(-2,4) lie on a circle of a radius 6 units and centre at c(3,5)?

Answer 1

distance b/w P and C

= root (x1-x2)2 + (y1-y2)2

= root (-2-3)2 + (4-5)2

= root (-5)2 + (-1)2

= root 25 +1

= root 26

since , distance is not 6 cm therefore the following point doesnot lie on circle.
