Question

for a circle with a radius of 8 ft find the arc lengths subtented by a central angle of pi/3

Answer 1

\( \color{Black}{\Rightarrow \Large {x \over 360} \times Circumference }\)

\(x\) is the angle, which is pi/3 here.

Answer 2

I suggest converting it to degrees first, or doing it with radians only.

Answer 3

\( \color{Black}{\Rightarrow \Large {x \over 2\pi} \times Circumference }\)

Answer 4

okay thanks! :)
