in a circle of radius 26, find the length of the arc spanned by a central angle of pi/4 radians. round your answer to 2 decimal places. use 3.1416 as an approx for pi.

  • trig -

    Recall that C = rθ
    Remember that for a whole circle, θ=2π, so C = 2πr

    Here, we have r = 26, θ=π/4

    c = 26 * π/4 = 13/2 * π = 20.42
