Help with part D! Thank you

A window has a shape bounded by a parabola above and a circular arc below. Find the area of the window. Assume the dotted line is the y-axis, and the solid gray line is the x-axis. 5.89 ft 10 ft 12.8 ft A. Find the distance from the x-axis to the top of the circle. Round the result to three decimal places. 1.01696 feet B. Write the equation of the circle. Leave your answer in the form (x - h)' + (y -k)? =2. (x - 0)' + (y+ 11.78304)2 =12.82 C. Write the equation of the parabola. Leave your answer in the form (x - h)' = a(y - k). y = -0.2356x + 5.89 D. Find the area of the window. Round the result to three decimal places. ft2
