B) 2.0 cm
C) 2.5 cm
D) 4.5 cm
Correct Answer: C
Solution :
The centre of the circle passing through A, B and C will be the point of intersection of the perpendicular bisectors PQ and PR of AB and BC respectively. Radius, \[BP=\sqrt{B{{Q}^{2}}+P{{Q}^{2}}}\] \[=\sqrt{{{2}^{2}}+{{1.5}^{2}}}\] \[=\sqrt{6.25}\] \[=2.5\]You need to login to perform this action.
