3.14×35.2+6.28×23.3+1.57×36.4
=3.14×35.2+3.14×2×23.3+3.14×1/2×36.4
=3.14×(35.2+46.6+18.2)
=3.14×100
=314
解:原式=3.14×(35.2+2×23.3+1/2×36.4)
=3.14×(35.2+46.6+18.2)
=3.14×100
=314
3.14×35.2+6.28×23.3+1.57×36.4
=3.14×35.2+3.14×2×23.3+3.14÷2×36.4
=3.14×35.2+3.14×46.6+3.14×18.2
=3.14×(35.2+46.6+18.2)
=3.14×100
=314
3.14*35.2=110.528
6.28*23.3=146.324
1.57*36.4=57.148
最后结果为314
