R is Ricci Tensor No, it's not, as shown by the material you cut and pasted. Ricci tensor is unit less No, it's not. If you express the Ricci tensor in locally Cartesian coordinates, its components have units of meters^-2. You should attribute the material you cut and pasted. The first quote seems to be from WP. | |

That depends entirely on where/how you plaster it. IIRC, triangles on the surface of a sphere can have total interior angles of 180 to 540 degrees, non-inclusive, depending mostly on their size relative to the sphere. | |
