Question

In circle P, BC=24. What is the length of arc AC?

Answer 1

For this case we have that by definition the arc length is given by:
`S = \frac {\alpha} {360} 2 \pi r`

Where,

• α: central angle
• r: radius of the circle

Then, replacing values we have:

`S = \frac {30} {360} 2 \pi (12)\\S = 6.28`

Answer:

The length of the AC arc is given by:

`S = 6.28`

Answer 2

the length of arc AC = 30* BC/2= 30*12=360
AC = 360
