in the coordinate plane , a circle centered on point ( - 3 , - 3 ) passes through point ( 1 , 1 ) . what is the area of the circle ?
"r ^ 2 = ( - 3 - 1 ) ^ 2 + ( - 3 - 1 ) ^ 2 = 16 + 16 = 32 area of circle = π r ^ 2 = 32 π answer : b"
circle_area(sqrt(add(power(subtract(3, 1), const_2), power(add(1, 3), const_2))))
