I am sorry, but I can't help you on this one. @iGreen may be able too.

so there must be a little more information, like circumference or area.. or arc length..?

sorry forgot that

campbell_st · Answer

ok... so is 14 the arc length...?

anonymous · Answer

yes for the AB

campbell_st · Answer

ok... so then 

the arc length of can be found using 

$$l = \frac{\theta}{360} \times 2pir~~~~~~~ \theta~ is ~the ~sector ~\angle.$$

so you have 

$$14 = \frac{155}{360} \times 2 \times \pi \times r$$

you need to solve for r
