OpenStudy (anonymous):

get the areas for both square and circle then calculate the ratio

OpenStudy (acxbox22):

probability=area of circle/area of square

OpenStudy (anonymous):

the A=254.47 of the circle and the square A=324 i think

OpenStudy (anonymous):

am i correct?

OpenStudy (♪chibiterasu):

How did you get those?

OpenStudy (acxbox22):

yes now put those two numbers over each other for the ratio of probability

OpenStudy (anonymous):

0.785 wwhich is 78.5%

OpenStudy (anonymous):

A=(pi)r^2 for circle and A=a^2 for square
