On a spherical globe of radius 10 units, the distance between two points A and B measured along the surface is 25 units. If the globe is uniformly expanded to a radius of 50 units, the distance between them along the surface in the same units would be:

If B is the center of a circle and lines AD and CD are tangent segments drawn from an external point D, then which of the following classifications apply to quadrilateral ABCD? (a) Kite (b) Cyclic quadrilateral (c) Rhombus (d) Trapezium
