Sly Cooper is making another daring escape after a heist! He is on top of a 112 meter building that is perpendicular to the ground. The angle of depression to a park bench is 15°. He plans to create a zip line from the top of the building to the park bench to escape. a) Sketch a picture of this scenario b) How long does the zip line need to be to the nearest tenth of a meter?

The central angle of this shaded sector measures 45 degrees, and the sector's area is 321 square inches. Kiran says, "We can find the area of the whole circle, the arc length of the sector, and the circumference of the circle with this information." Priya says, "But how? We don't know the circle's radius!" Do you agree with either of them? Explain or show your reasoning. Calculate as many of the values Kiran mentioned as possible.
