The center of the circle is O, and RS = ST = 4. What is the length of arc RWT?
A. \(\frac{4\pi}{3}\)
B. \(\frac{8\pi}{3}\)
C. \(\frac{16\pi}{3}\)
D. \(4\pi\)
E. \(8\pi\)
Here,
RS = ST = 4
Therefore TO = RO = 4
Hence \(\triangle\) STO = \(\triangle\)SRO = Equilateral \(\triangle\)
The \(\angle\)TOR =120
ARC TWR = \(2\pi * Radius * \frac{240}{360} = 2\pi * 4 *\frac{240}{360} = \frac{16\pi}{3}\)
