Answer:

Step-by-step explanation:
Assuming this complete problem: "A cell tower is located at (-8, 4) and transmits a circular signal that covers three major cities. The three cities are located on the circle and have the following coordinates: G (-4, 7), H (-13, 4), and I (-8, -1). Find the equation of the circle"
For this case the generla equation for the circle is given by:

From the info we know that the tower is located at (-8, 4) so then h = -8 and k = 4, so then we need to find the radius. So we have the equation like this:
If the 3 points are on the circle then satisfy the equation. We can use the first point (-4,7) and if we replace we can find the value for 

So then 
And if we replace the second point we got this:

And for the third point we have:

And we got the same result.
So then our final equation is given:

Answer: 216 ml
Step-by-step explanation:
400 grams = 480 ml
180 grams = ?
Since the value of 180 grams in milliliters is unknown, let the unknown be Z
Thus, 400 grams = 480 ml
180 grams = Z
To get the value of Z, cross multiply
Then, Z x 400 grams = 480ml x 180 grams
400Z = 86400
Divide both sides by 400
400Z/400 = 86400/400
Z = 216
Thus, 180 grams is equal to 216 milliliters.
The exact form is -15/28 and the decimal form is -0.535
