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 : a"
circle_area(sqrt(add(power(subtract(3, 1), const_2), power(add(1, 4), const_2))))
