In the drawing attached, the shaded region is bound by the arc of a circle of radius 50 yards and a line that is parallel to the thick line tangent to the arc. If |BC| =25 yards, the area of the shaded region in square yards is between
(A) 850 and 1000 (B) 1000 and 1150 (C) 1150 and 1300 (D) 1300 and 1450 (E) 1450 and 1600
Given BC = 25, we can calculate AB, comes out to arnd ~43.5 (drawing a line from center of the circle to A and midpt of AB and then using pythagoras).. Given AB, we can calculate shaded area = ~ 1/2 (43.5 * 25) ~ 1100
