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 翻译一下在做,
答
求出：一个地面由x轴和曲线y=4-x^2围成、横截面是垂直于x轴的正三角形且其中一边在地面上的体积。
答
求出下面图形的体积,其底面为x轴和曲线 y=4-x^2围成,它的横截面是垂直于x轴的等边三角形,其中一边在底面上.
这个题看起来还有点难,是高等数学里的二重积分问题
