Angles on a straight line add up to 180 degrees.
Every circle has a point called the centre. A straight line drawn through the centre and extending both ways to intersect with the circle at opposite points is called the diameter. A straight line drawn from the centre to intersect with one point of the circle is called the radius. In this case, the length of that straight line is 12 inches.
An infinite number of lines can be drawn through a single point, but only one through two points (of course, if the points don't have the same coordinates).

i think just one line, as its defenition of straight line

1 straight line. An infinite number of curved lines.
Every circle has a point called the centre. A straight line drawn through the centre and extending both ways to intersect with the circle at opposite points is called the diameter. A straight line drawn from the centre to intersect with one point of the circle is called the radius. In this case, the length of that straight line is 12 inches.
In principle, yes an infinite number can be drawn, but in practise you would run out of graphite to draw the lines before getting to an infinite number. Even if you converted all the matter in the universe to graphite (using some Star Trekian style technology), you would still run out.

Yes. You can draw infinitely many straight lines from each point.

the answer is one
One.
Infinitely many.
