Question

What is the arc length of the arc subtended in a circle with radius 6 and an angle of 7pi/8

Answer 1

@MARC_D dont i just multiply them ?

Answer 2

formula to find length of arc\[s=r \theta\]

Answer 3

where
r=radius
theta=angle in radian form

Answer 4

r=6 and theta= 7pi/8?

Answer 5

and do i just multiply

Answer 6

yep

Answer 7

\[s=6(\frac{ 7\pi }{ 8 })\]

Answer 8

so the answer is 21pi/4?

Answer 9

yup :)
