Ex 5.1, 4 What is the least possible radius of a circle through two points A and π΅? We have to find the smallest radius of a circle which passes through two points Smallest radius would be when AB is the diameter i.e. when center lies on line segment AB Thus, Smallest Radius = π·πππππ‘ππ/2=π¨π©/π Letβs visualize it RADIUS CONTROLS Radius (r): 3.0 cm Least Possible Radius! AB is the diameter of this circle. Distance . Minimum r .
