Answer:
Step-by-step explanation:
Outer diameter=14cm radius=14/2=7cm(R)
Thickness=2cm
Inner diameter =14-2+2=14-4=10cm radius=10/2=5(r)
Height=14
Capacity= π×r×r×h(volume of a cylinder) =22/7×5×5×14=440cube.cm(1)
Volume of the metal=volume of outer cylinder - volume of inner cylinder
=π×R×R×h - 440. (From (1))
=22/7×7×7×14 - 440
=2156 - 440
=1716 cube.cm
