Find the area of the circle if the side length of square is 10.
Let connect the midpoints of sides AD and BC with a line segment MN
AM = sqrt(AB2 + BN2)
MN = sqrt(AM2 + AN2) (This is your diameter)
Above post is no good
AN = sqrt(52 + 102)
Angle ANM = arctan(5 /10)
AM = 5 / cos(ANM)
MN = sqrt(AN2 + AM2)
