Which case would be the most appropriate for a drum with a volume of 14,000 cm3?Volume of a cylinder: V = area of the base x heightV = πr2hπ = 3.14

Answer:Case (c) will be the most appropriate  for a drum with a volume of 14,000 cm³Step-by-step explanation:The drum is in the shape of cylinder so, we will calculated its volume using formula : V = πr²h , where r is radius of cylinder and h is height of cylinder.In case (a) Given height is 300mm ( 30 cm ) and diameter is 200mm ( 20 cm )so, radius ( r ) is calculated as d/2r = 20/2r = 10 cmso, volume is V = πr²h = (3.14)*(10)²*30 = 9420 cm³In case (b) Given height is 30 cm and diameter is 400mm ( 40 cm )so, radius ( r ) is calculated as d/2r = 40/2r = 20 cmso, volume is V = πr²h = (3.14)*(20)²*30 = 37680 cm³In case (c) Given height is 250mm ( 25 cm ) and diameter is  32 cmso, radius ( r ) is calculated as d/2r = 32/2r = 16 cmso, volume is V = πr²h = (3.14)*(16)²*25 = 20096 cm³Hence, the case (c) will be the most appropriate  for a drum with a volume of 14,000 cm³
