    Part 1)Find the length s to the nearest tenth

    we know that
    [length of a circumference]=2*pi*r
    for r=3 in
    [length of a circumference]=2*pi*3——> 18.84 in

    if 2*pi radians (full circle) has a length of————> 18.84 in
    (5*pi/3) radians——————————> x
    x=(5*pi/3)*18.84/(2*pi)——–> x=15.7 in

    the answer Part 1) is
    15.7 in

    Part 2)What is the probability he will draw a blue tile on both draws?

    wehave a bag of 5 red tiles, 3 yellow, 4 blue and 3 green
    total tiles —–> 15

    4 blue out of 15
    1st draw is 4/15
    2nd draw is 4/15
    (4/15)*(4/15)—–> 16/225

    the answer Part 2) is
    16/225
