Sheryl is getting ready for spring break and she can't help but notice the shape of the inner-tube that she is packing. Sheryl is trying to figure out the best way to pack it. She measures the radius of the circular cut out and it measures to be 7 inches. Then she measures from the center to the outer part of the tube, which measures at 15 inches. What is the area of the green inner-tube? Round to the nearest hundredth, if necessary.
