what is the equation of a circle of radius 5 units centered at ( 3 , 2 ) ?
the equation of a circle with center at ( a , b ) and radius r is ( x - a ) ^ 2 + ( y - b ) ^ 2 = r ^ 2 = > answer = ( x - 3 ) ^ 2 + ( y - 2 ) ^ 2 = 5 ^ 2 solving , , we get the equation in answer choice e .
subtract(subtract(power(5, const_2), power(3, const_2)), power(2, const_2))
