Question

Use the arc length formula and the given information to find r. Show your work for full credit.
s = 8.1 ft θ = pi/3 rad r = ?

Answer 1

use the arc formula

so what is the arc formula?

Answer 2

s = rθ is the arc formula

Answer 3

and to solve that for "r" would turn it into?

Answer 4

r = s/θ?

Answer 5

yep

so, with the given info

r = \(\large \frac{8.1}{pi/3}\)

Answer 6

is that the final answer?

Answer 7

thats all the parts of the answer; how you simplify it is up to you

Answer 8

ohh okay thank you

Answer 9

your welcome, good luck ;)
