For a certain car, the distance traveled by the car while trying to stop is given by the equation d = 0.09r² + r, where r is the speed of the car in miles per hour, and d is the distance needed to stop in feet. Find the total number of feet needed to stop the car traveling at 46 miles per hour. Round any approximate value to 2 decimal places.
