Outer radius=60cm
Inner radius =50cm
Outer radius=40cm
Inner radius=36cm
Volume of inner=1/3*3.14*50*50*36
. 94200 cubic centimetre
Volume of outer=
1/3*3.14*60*60*40
=150720 cubic cm
Volume of the wood is=OUTER VOLUME-INNER VOLUME
(150720-94200)cubic cm.
=56520 cubic cm.
Inner radius =50cm
Outer radius=40cm
Inner radius=36cm
Volume of inner=1/3*3.14*50*50*36
