10. Into a circular drum of radius 4.9 m and height 3.6 m, how many full bags of grain can be emptied if the space required for each given bag is 1.8 m³? (Take π = 3.14)
The volume of the drum is V = πr²h = 3.14 × 4.92 × 3.6 = 206.6 m³. The space required for each bag is 1.8 m³. Therefore, the number of full bags of grain that can be emptied into the drum is 206.6 ÷ 1.8 = 115.3 ≈ 115 bags.
