Answer:number 2. c. 16/225

Step-by-step explanation:i took the exam

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) is15.7 inPart 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) is16/225
