Answer 1

the angle isnt important, what you can tell from this is that ST covers the radius twice, since r is the midpoint of the circle (it is the midpoint right?) so then divide the length of ST by two:

r=7(pi)

and put it into the equation 2(pi)r

so 14(pi)^2

Answer 2

\[\frac{14\pi}{126}=\frac{C}{360}\]
solve for
C
