On the lacrosse field, the circular region around the net, called the
crease, is an area that only the goalie is allowed to be in. The crease
is 18 feet in diameter. If the goalie is centered in the crease located
at (30, 15) on the coordinate plane, what is the equation of the
crease?
O (x+30)2
+ (y-15)2 = 9
O (x+15)2 + (y+15)2 81
O (x-30)2 + (y-15)2 = 81
O (x-15)2 + (y-30)2 = 18
