A) An elliptical-shaped whispering gallery has two chairs positioned at the foci of the ellipse, 6 m apart. The width of the room, measured along its minor axis, is 8 m. What equation represents the elliptical-floor if its center is at the origin and its major axis is horizontal?
B) The area of an ellipse is A = πab, where a is the semi-major axis, and b is the semi-minor axis. What is the area of the floor of the room? Round your answer to the nearest tenth.
