解：1.6÷2＝0.8（米），
3.14×0.8²×1.6
＝3.14×0.64×1.6
＝3.21536（立方米）
答：这个水池能装3.21536立方米。
能装约3.2立方米的水。
解析：因为 圆柱形水池的容积=底面积X高
=半径平方XπX池深
=(1.6/2)^2X3.14X1.6
=0.8^2X3.14X1.6
=0.64X3.14X1.6
=3.21536
圆柱形体积等于πr²h.
π=3.14
r=d/2=1.6/2=0.8
h=1.6
πr²h=3.14×0.8²×1.6
=3.22m³
=3.22吨
答:能装水3.22吨。
这是算圆柱的体积
圆柱体积，等于底面积乘以高。
所以容积是3.14*0.8*0.8*1.6约等于3.22立方米
1.6÷2x3.14159x1.6=4.02
