Quizplus · Accepted Answer

The center of a sphere can be found by looking at the equation of the sphere in Cartesian coordinates, which is (x - h)^2 + (y - k)^2 + (z - l)^2 = r^2, where (h, k, l) is the center of the sphere and r is the radius. Looking at the given equation of the sphere, we can see that the x, y, and z terms all have values of TB6988_11, which means the center of the sphere is located at TB6988_11 in all three dimensions. Therefore, the best choice for the center of the sphere is D.
