yes

Answer 4

tell me what you get :)
[radius = 4]

Answer 9

I got a little sidetracked, sorry ^_^"

the circle is correct! :)

try the square again, side = 8
area of square = (side)*(side)

Answer 10

oh ok

Answer 11

it's 64

Answer 12

yes :)
now divide (area of circle) by (area of square) = the probability you want

Answer 13

it's 0.785

Answer 14

multiply by 100 to make it a percent ^_^

Answer 15

78.5%

Answer 16
