A circle is shown. 2 raddi are drawn. A chord connects the points of the radii on the circle to each other to form a triangle. The radii have lengths of 5 feet. A perpendicular bisector cuts through an angle with a measure of 72 degrees and cuts the opposite side of the triangle into 2 equals parts with measures of 2.9 feet. The length of the bisector is 4 feet. The space between the chord and the outline of the circle is shaded. What is the area of the shaded portion of the circle? (5π – 11.6) ft2 (5π – 5.8) ft2 (25π – 11.6) ft2 (25π – 5.8) ft2
