x tells you how much left or right you go from the origin
y tells you how much down or up you go from the origin
so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
the pertinent area formula is a = πr², where r is the radius.
here, a = π(6.35 m)² = 40.32π, or approximately 126.66 m²
