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
is an important application in finding the area in the plane(the two dimensional area).This means the application of integrals to the computation of areas in the plane can be extended to the three dimensional solid.We have another important application is computation of certain volumes in space....
