竖式 3. 1 4 x 3 6 ______________ 1 8 8 4 9 4 2 ———————— 1 1 3. 0 4

3.14×36+3.14×47+3.14×17 =3.14×(36+47+17) =3.14×100 =314 明白请采纳,有疑问请追问! 有新问题请求助,谢谢!

6!/3!x3!等于少 =(1*2*3*4*5*6)/(1*2*3*1*2*3) =(4*5*6)/(1*2*3) =20 6!/2!X2!X2! =(1*2*3*4*5*6)/(2*2*2) =1*3*5*6 =90 3.14x2x36等于多少 请详细描叙问题

提取公因数3.14,则原式变为 3.14X[-35.2+2X(-23.3)-0.5X36.4] =3.14X[-35.2-46.6-18.2] =3.14X(-100) =-314

720/(2x3.14x0.36)=318.3≈318(圈)
