-3.14x35.2+6.28x(-32.9)-33.26+36.4=-314

-3.14x35.2+6.28x(-23.3)-1.57x36.4 =-3.14x35.2+3.14x(-46.6)-3.14x18.2 =-3.14x(35.2+46.6+18.2) =-3.14x100 =-314

3.14*40*x/180=52.36 x=52.36*180/(3.14*40) x≈75.038

3.14x(0.05÷2)²x36 =3.14x0.025²x36 =3.14x0.000625 x 36 =0.07065 希望我的回答对您有帮助,满意请采纳,谢谢。

3.14 x22+1.57x36+(-6.28)x15 =3.14x22+1.57x2x18-3.14x2x15 =3.14x(22+18-30) =3.14x10 =31.4
