数学六年级下册第三单元《圆柱的体积》课时练习

数学六年级下册第三单元《圆柱的体积》课时练习1.填空题。

(1)为了推导圆柱的体积,我们可以将圆柱转化为( ),转化后立体图形的底面积等于圆柱的( ),它的高等于圆柱的( ),它的体积等于圆柱的( )。因为长方体的体积=( )×(),所以圆柱的体积=( )×()。

(2)一个圆柱的底面积是12平方厘米,高是2.5厘米,这个圆柱的体积是( )立方厘米。

2.求下列圆柱的体积。(单位:厘米)

3.有20根底面半径是6厘米、长是2米的圆木。这些圆木的体积一共是多少立方米?

答案:

1.(1)长方体底面积高体积底面积高底面积高

(2)30

2.282.6立方厘米 401.92立方厘米125.6立方厘米

3.6厘米=0.06米

3.14×0.062×2×20=0.45216(立方米)
