find the radius of the black hole that is made from our solar system's sun's destruction.
(I apologize for my terrible english, tell me if question is not clear..)

I believe there is basically no radius, because a black hole is an extremely large amount of matter packed into an TINY space... isn't this more of astronomy?

it has something to do with "escape velocity".. as this question was  under "escape velocity" topic
when i  equated (actually, greater than) escape velocity with  speed of light... i got a ratio m:r of any block hole...
but i dont think that putting the mass of sun at "m" will give the right ans...i mean how can i just mess around with thing like "BLACK HOLE"

BTW putting the mass of sun at m given me right ans.. (acc. to ans book, "clarity matters more than answers," right?)

i asked this question because i just wanted to know if:
"is it sensible to just directly put the mass of sun there??"
yes or no

our sun doesn't become a black hole, but a red dwarf. The answer can be found using blackhole density and the suns mass the find the volume. Use the volume in the circle volume formula to find radius
