MCQ
The length of the arc $OP$ is :
- A$16.28\ cm$
- B$12.28\ cm$
- C$15.28\ cm$
- ✓$19.28\ cm$
✓
Answer
Correct option: D.
$19.28\ cm$
Arc length $=\frac{\theta}{360}2\pi \text{r}$
$=\frac{65}{360}\times2\times\pi\times17$
$=19.28\text{ cm}$
$=\frac{65}{360}\times2\times\pi\times17$
$=19.28\text{ cm}$
