what basically happens is that gravity bents space & time fabric. the light travels parallel to space & time fabric so at a point the fabric is stretched and light have to travel twice as long so that's why they say light cannot escape a black hole. As Eisenstein said that c is the optimum speed...
i see it forms a single circle!
if the perimeter is (25.20983226924521) + 2*3.1415926535897932384626433832795 is
31.493017576424796476925286766559 not even close to 34.408
i do not understand what's wrong
so if i draw tangents on the outside it will join and form a pentagon and the internal angles are 540. so what am i doing wrong? please help me!
in the picture there are 5 mines that stick out. so the internal angles is 540 degrees so the length of the arc. rather than 360 degrees this is 540 degrees that's how i got ~ 9.424
and also let's say i have multiple points refer the pic
and the points are
x y
1 4
3 2
7 9
5 4
9 5
6 7
9 1
11 8
the radius is 1 unit
i did a convex hull algorithm and found the perimeter and added the arc length. since it is a 5 sided polygon the interior angles are 540 degrees
the total...

so, i need to know the equation for finding the length of the tangent.
please read...
