18. Extra Credit: The surface S is the part of the sphere x2+y2+z2=a2 that lies inside the cylinder x4+a2(y2−x2)=0. Sketch it and show that its area equals 2a2(π−2). HINT: Use cylindrical coordinates and take into account that S is symmetric with respect to both the xz - and yz-planes. Also, at some appropriate time(s) use the formula 1+tan2θ= cos2θ1
