Question

Use the diagram below to find the probability that a point chosen at random is in the shaded area. Enter the answer in simplified fraction form; example: 3/20.

Answer 1

I got 100.4?

Answer 2

well i'll show you my steps.

find area of small circle.
sc=pi 2^(2),

then the lil arc segment that is shaded is just

ms= pi*4^2-sc

The area of the big circle is

bc = pi*6^2

so the answer is bc/ms

Answer 3

and i got 3
pi*6^2/(pi*4^2-pi*2^2)

Answer 4

so 37.7/113.09 ?

Answer 5

well i guess if you flip my ratio it makes more sense and it is 1/3 = .33333333333333

Answer 6

1/3 makes more sense than 3 or 100.4 :D wouldn't you agree. It is suppose to be a ratio.

Answer 7

yeah, thanks for your help :)

Answer 8

De nada :D
