Using the Law of Sines (sina/A=sinb/B=sinc/C for any triangle)

sinR/30=sin96/54

sinR=30sin96/54

R=arcsin(30sin96/54)°

R≈33.5° (to nearest tenth of a degree)

We are given the length of AC and AB to be 20 and 6, respectively, so we can subtract 6 from 20 to find BC to be 14 cm.

The circumference of a circle is equal to $2 \pi r$

$C=2 \pi (14) = 28 \pi$
