1. Answer:

number 2. c. 16/225

Step-by-step explanation:

i took the exam

2. 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
