Area circle = pi r^2 pi 6^2 = 36pi is the area of NOT the shaded; which helps

OpenStudy (geometry_hater):

then subtract that from the area of square right?

OpenStudy (amistre64):

yes area of a square is side*side 12*12 = 144 for total area

OpenStudy (amistre64):

144-36pi -------- is the probability that covers the shaded part 144
