Question

What is the arc length when Ɵ- pi/3 and the radius is 5 cm?
A. 10pi/3 cm
B. 16pi/3 cm
C. pi/3 cm
D. 5pi/3 cm

Answer 1

when Ɵ = pi/3 I mean.

Answer 2

\[Arc\ Length = \theta * r\]

Answer 3

So its D?

Answer 4

Yup!

Answer 5

Thank you!

Answer 6

I have like 3 more if you could try to help

Answer 7

If it helps you think about it, the 'arc length' of the entire circle is the same as the perimeter, which is 2*π*r. Since there are 2π radians to get around the circle, it makes sense that the arc length would just be angle (in radians) times the radius.
