The endpoints of a diameter of a circle are located at(-3,6) and (7,-12). What is the equation of the circle? A. (×+2)2+(y+3)2=square 106 B. (X-4)2+(y+6)2

.

Step-by-step explanation:

It is given that the endpoints of a diameter of a circle are located at(-3,6) and (7,-12). It means center of the circle is the midpoint of (-3,6) and (7,-12).

The center of the circle is (2,-3).

Radius is the distance between center and the endpoint of diameter. So, radius is equal to the distance between (2,-3) and (-3,6).

The standard form of the circle is

where, (h,k) is center and r is radius.

Substitute h=2, k=-3 and in the above equation.

Therefore, the required equation of circle is .

this is not the answer this is just a question. is this middle school math?

step-by-step explanation:

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
