True enough but not looking for 'exact' numbers.

The Milky Way’s center is 26,000 light-years from Earth, and Sgr A* is measured to be about 14 million miles across. This means that the black hole itself would easily fit inside the orbit of Mercury. How much mass is crammed inside this relatively small space? The lower mass limit of the black hole itself is calculated to be more than 40,000 Suns. However, the radio-emitting part of Sgr A* is a bit bigger, about the size of the Earth’s orbit around the Sun (93 million miles), and weighs much, much more – 4 billion Suns.

The center of our galaxy is called Sagittarius A*, a massive source of radio waves that is believed to be a black hole with the mass of 40,000 Suns and measures 22,5 million kilometers (14 million mi) across – about the size of Mercury's orbit. But this is just the black hole itself.
All of the mass trying to get into the black hole – called the accretion disk – forms a disk that has a mass of 4 million Suns, and would fit inside the orbit of the Earth.
So if what they're calling a black hole is only about 40,000 suns in mass, that's well within the possibility of a plasmoid as envisioned by plasma cosmologists. And the rest is the mass of material spiraling in along filaments like plasma cosmologists theorize carrying energy towards the plasmoid and growing ever denser the closer the filaments get to the plasmoid. In plasma cosmology, the same thing is theorized to happen on a smaller scale during the formation of stars. Note that when too much plasma and energy are carried into the plasmoid early in the development of the galaxy or star when there's so much plasma around, the plasmoid will produce jets to carry away the excess. These are the quasars and, on the scale of stars, Herbig Haro object jets. This is the way both developing galaxies and stars shed the excess angular momentum that would otherwise prevent formation.
