volume of d metal = outer volume - inner volume
= 4/3 pie r3 - 4/3 pie R3
= 4/3 pie (r3 - R3)
= 4/3 x 22/7 (123 - 103)
= 4/3 x 22/7 ( 1728 - 1000)
= 4/3 x 22/7 x 728
= 305.66 cm3

Answer:
volume,Outer radius (R) = 12 cm,Inner radius (r) = 10 cm,Volume of hollow sphere = ,(4/3) ,Π (R,³ - r³), = ,(4/3)(22/7), (12,³ - 10³), = ,(88/21), (1728, - 1000), = ,(88/21), (728,), = ,(64064/21), = ,3050.67 ,cm³
Step-by-step explanation:
