**Raffaele**, Thursday, March 28, 2013 at 7:44amin a trapezoid like this the sum of two opposite sides is equal to the sum of the other two

thus the sum of the bases is 50

area = (1/2)(sum of the bases) x height

height = (2 area)/(sum of the bases)

height = 1200/50 = 24

height is also the diameter of the circle

therefore its radius is 12
