Answer:

Answer:

in the fig 'B' is center

ABCD is rhombus

AD=AB=BC=BD =8cm ( radii)

In rhombus , diagonals are

bisector each other out 90°

BD=BO+OD=4+4=8cm

In Right angle  {∆}^{le} AOD

↦AD²=AO²+OD²

↦(8²)=AO²+(4)²

↦AO²=64-16=48

↦AO²= \sqrt{16 \times 3}  = 8 \sqrt{3} cm

ஃ The longest diagonal is 8 \sqrt{3}
