Answer 1

Go by a process of elimination. I think we can safely say it's not 115.3

Answer 2

Well that idnt help well.

Answer 3

That line that measures 19 looks like it's longer than a radius.

Answer 4

im bad at maths

Answer 5

No you're not, just look at it like a game, try to find a reason to rule answers out.

Answer 6

Process of elimination won't always be helpful, So look at what you know.
If you look at half of the line that measures 19 you can make a triangle whose hypotenuse is equal to the radius.

Answer 7

so this is whats given

Answer 8

do you know the length of that?

remember that the chord is bisected perpendicular from a line from the center

Answer 9

I think you're complicating things for nothing.

Answer 10

ok well...
theres a theorem that states in a circle, the perpendicular bisector of a chord passes through the center of the circle
which means 19/2= 9.5

and using the pythagoreom theorem, you can find x, which would be the radius
so
5^2 + 9.5^2=x^2
solve for x
