2.2兀x15÷1%等于几

2.2兀x15÷1% =2.2*3.14*15÷0.01 =2.2*15*3.14÷0.01 =(2+0.2)*15*3.14÷0.01 =(2*15+0.2*15)*3.14÷0.01 =(30+3)*3.14÷0.01 =(30*3.14+3*3.14)÷0.01 =(94.2+9.42)÷0.01 =103.62÷0.01 =10362

请采纳

15×11=150+15=165

36x15 =36x30÷2 =1080÷2 =540

不能这么说 厘米和寸都是长度单位,但是厘米x厘米是面积单位,这是两个不同维度的单位,不能换算 1寸=3.3333333333333厘米 1英寸 = 2.54厘米 1英寸=0.762寸

解:3.4x87+3.4x15-3.4x2 =3.4x(87+15-2) =3.4x100 =340 (6.02+2.8)÷4-2.05 =1.505+0.7-2.05 =2.205-2.05 =0.155

1/3×3.14×(10÷2)×15 =1/3×3.14×5×15 =(1/3×15)×(3.14×5) =5×15.7 =78.5

120-4.32X15+5.1÷0.85 =120-64.8+6 =61.2 8.7X0.72÷(2.9x1.8X2.5) =8.7X0.72÷13.05 =6.264÷13.05 =0.48

5/6×1/15÷7/18 =1/18×18/7 =1/7 (1/15+1/7)x15x7 =1/15 x15x7+ 1/7 x15x7 =7+15 =22 10/3-2/3x9/5-4/5 =10/3-6/5-4/5 = 10/3-(6/5+4/5) = 10/3-2 =4/3 7/9÷11/5+2/9x5/11 = 7/9×5/11 +2/9x5/11 = 5/11 ×(7/9+2/9) =5/11 (1/6+7/15)÷2/5+...
