Find the value of integral (+3 (x + y + z)ds, where C is parameterized by ŕ(t) = (4√√2 cos(2t), 9 sin(2t), 7 cos(2t)) for 0 ≤t≤”.

By expanding (xh)2+(yk)2=r2, we obtain x22hx+h22ky+k2r2=0. When we compare this result to the form x2+y2+Dx+Ey+F=0, we see that D=2h,E=2k, and F=h2+k2r2. Therefore, the center and the length of a radius of a circle can be found by using h=D2,k=E2 and r=h2+k2F. Use these relationship to find the center and the length of the radius of each of the following circles. x2+y2+4x14y+49=0
