If 12 gallons cost $36. how much would 8 gallons cost?

$24

Step-by-step explanation:

12 x 3 = 36

8 x 3 = 24

The formula is ( x − h) 2 + ( y − k) 2 = r 2 . What is the equation of the circle pictured on the graph below? Since the radius of this this circle is 1, and its center is the origin, this picture's equation is. Look at the graph below, can you express the equation of the circle in standard form?

Step-by-step explanation:

The equations of the circle is of the form: (x - h) 2 + (y - k) 2 = r 2. where (h , k) is the center of the circle and r its radius. As an exercise, you need to find an equation to the circle generated. And you can check your answer.
