(1)抹水泥部分的面积是多少平方米?

(2)蓄水池能蓄水多少吨?(每立方米水重1吨)

答案

解:(1)水池的侧面积:

31.4×2.4=75.36(平方米);

水池的底面积:

3.14×(31.4÷3.14÷2)2,

=3.14×52,

=3.14×25,

=78.5(平方米);

抹水泥部分的面积是:

75.36+78.5=153.86(平方米);

答:抹水泥部分的面积是153.86平方米

(2)水池的体积:

3.14×52×2.4,

=3.14×25×2.4,

=188.4(立方米);

蓄水池能蓄水:

1×188.4=188.4(吨);

答:蓄水池能蓄水188.4吨。
