Jason and Gabriella are out for a walk on a rainy day. They come to the edge of a large circular puddle that has a radius of 4 feet. Jason is wearing boots, so he walks straight through the center of the puddle to the other side. Gabriella forgot to wear her boots, so she walks around the outside of the puddle to meet Jason on the other side. How much farther, in feet, did Gabriella walk than Jason? (Use 3.14for π )
