The pool at a park is circular. you want to find the equation of the circle that is the boundary of the pool. find the equation if the area of the pool is 500 square feet and (0, 0) represents the center of the pool.

A3-dimensional figure has a square base and 4 lateral faces that meet at a point. explain the difference between the cross sections when a slice is made perpendicular to the base through the vertex, and when a slice is made perpendicular to the base and not through the vertex
