A sidewalk bounds a circular playground at GeoCity Park. Parents can exercise by walking around on the sidewalk, while watching their children play. If the inner edge of the sidewalk is 1,256.64 meters around, approximate the area of the playground inside the circular path.

Graph the equation by plotting point x=2

Expresa commuter train leaves downtown sation and travels at a average speed of 55 miles per hour towards the north side sation, which is 50miles away. thirty minutes later, express commuter train #7 leaves north side and travels at a average speed of 35miles per hour towards downtown sation. at the moment the two trains pass each other, how far(in miles) is train #12 from the downtown sation and how long(in minutes) has the #12 train been traveling

What is the total area of the figure?
