Now, distance between origin i.e., O(0, 0) and P(5, 0), OP = √(x₂ - x₁)² + (y₂ - y₁)² OP = √(5 - 0)² + (0 - 0)² = √5² + 0² = 5 = Radius of circle and distance between origin O(0, 0) and Q(6, 8), OQ = √(6 - 0)² + (8 - 0)² = √6² + 8² = √36 + 64 = √100 = 10 Chapter 7: Coordinate Geometry - Exercise...
