Answer:

OD=3 cm

OD=3 cmAB=8 cm

OD=3 cmAB=8 cmRadius =OB

OD=3 cmAB=8 cmRadius =OBIn △OBD

OD=3 cmAB=8 cmRadius =OBIn △OBDOB

OD=3 cmAB=8 cmRadius =OBIn △OBDOB 2

OD=3 cmAB=8 cmRadius =OBIn △OBDOB 2 =BD

OD=3 cmAB=8 cmRadius =OBIn △OBDOB 2 =BD 2

OD=3 cmAB=8 cmRadius =OBIn △OBDOB 2 =BD 2 +OD

OD=3 cmAB=8 cmRadius =OBIn △OBDOB 2 =BD 2 +OD 2

OD=3 cmAB=8 cmRadius =OBIn △OBDOB 2 =BD 2 +OD 2 ⟹OB

OD=3 cmAB=8 cmRadius =OBIn △OBDOB 2 =BD 2 +OD 2 ⟹OB 2

OD=3 cmAB=8 cmRadius =OBIn △OBDOB 2 =BD 2 +OD 2 ⟹OB 2 =4

OD=3 cmAB=8 cmRadius =OBIn △OBDOB 2 =BD 2 +OD 2 ⟹OB 2 =4 2

OD=3 cmAB=8 cmRadius =OBIn △OBDOB 2 =BD 2 +OD 2 ⟹OB 2 =4 2 +3

OD=3 cmAB=8 cmRadius =OBIn △OBDOB 2 =BD 2 +OD 2 ⟹OB 2 =4 2 +3 2

OD=3 cmAB=8 cmRadius =OBIn △OBDOB 2 =BD 2 +OD 2 ⟹OB 2 =4 2 +3 2 ⟹OB=5 cm

OD=3 cmAB=8 cmRadius =OBIn △OBDOB 2 =BD 2 +OD 2 ⟹OB 2 =4 2 +3 2 ⟹OB=5 cmRadius=5 cm
