radius, r = 32 cm
Triangle ABC is an equilateral triangle
The centroid of a triangle divides the median in the ratio 2:1
In an equilateral triangle, the median and altitude coincide
So AD passes through centre O and is the perpendicular bisector of BC
AO/OD =2/1
32/OD = 2
OD = 16cm
AD = AO +OD
= 32+16=48cm
