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?
we have 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
