【摘要】 用V=π∫_a^bf²（x）dx可求得连续曲线y=f（x）的弧AB与直线x=a,x=b及x轴所围成的平面图形绕x轴旋转一周得到的旋转体的体积。若x轴推广为一般的直线y-y₀=k（x-x₀）,其它条件不变,其旋转体的体积可由求得。更多还原

【Abstract】 It can get radian About consecutive curve y = f(x) by V = An plane figure which Radian AB and straight line x = a x = b and axis revolves a circle around X axis, the volume of objects in revolving shape comes out. If x axis is a general straight line y-y0 = k(x-x0) other terms are constant, the volume of objects in revolving shape can get fromv=.更多还原
