求出下面圖形的體積,其底面為x軸和曲線 y=4-x^2圍成,它的橫截面是垂直于x軸的等邊三角形,其中一邊在底面上.
這個(gè)題看起來(lái)還有點(diǎn)難,是高等數(shù)學(xué)里的二重積分問(wèn)題
AP:find the volume of a solid whose base is the region
AP:find the volume of a solid whose base is the region
find the volume of a solid whose base is the region between the x-axis and the curve y=4-x^2,and whose cross-sections perpendicular to the x-axis are equilateral triangles with a side that lies on the base 翻譯一下在做,
