<section id="description">菲尔糖果制造商正在制作一批新的巧克力糖果。每个糖果中心的形状类似于由以下等式定义的旋转椭圆体：b2x2 + b2y2 + a2z2 = a2b2。 <p>菲尔想知道需要多少巧克力来覆盖一个糖果中心，用一层厚厚的巧克力涂层。如果a = 1 mm且b = 1 mm，则所需的巧克力量为</p><pre> <code>283 π mm3</code> </pre><p>如果a = 2 mm且b = 1 mm，则所需的巧克力量约为60.35475635 mm3。 </p><p>如果a = 3 mm且b = 1 mm，则找出所需的mm3巧克力量。将数字舍入到小数点后面的小数点后8位。 </p></section>
