in the coordinate plane , a circle centered on point ( - 3 , - 4 ) passes through point ( - 1 , 1 ) . what is the area of the circle ?
r ^ 2 = ( - 3 + 1 ) ^ 2 + ( - 4 - 1 ) ^ 2 = 4 + 25 = 29 area of circle = π r ^ 2 = 29 π answer : c
circle_area(sqrt(add(power(subtract(3, 1), const_2), power(add(1, 4), const_2))))
