Hi
This Question is already discussed - but want to discuss one more time so opening a new thread -
The points R, T, and U lie on a circle that has radius 4. If the length of arc RTU is 4*Pi/3 , what is the length of line segment RU?
A. 4/3
B. 8/3
C. 3
D. 4
E. 6
i was solving the below mentioned way -
Radius - 4
So circumfrence - 2*Pi*R -> 8*Pi
Length of RTU - > 4*Pi/3
So length of RU shd be circumfrence - RTU -> 8*Pi -4*Pi/3
but this is not working, not able to get answer as mentioned in choices.
Can you please elaborate - how am doing it wrong and can you please suggest solution also .
