Answer:

Step-by-step explanation:
Equation of circle with center (a , b) and radius, r is :

Given : a = 0 , b = - 4
Step 1 : Find the radius.
Given ( 6 , 0 ) lies on the circle. Therefore the distance between the center (0 , - 4) of the circle and ( 6 , 0 ) gives the radius of the circle.


Step 2 : Equation of circle.

Answer and Step-by-step explanation:
The answer is attached below
Answer:
$23.54
Step-by-step explanation:
12.95+2.76+7.83=23.54
18.386 rounded to the nearest hundredth would be 18.39
From both sides of the equation, 4 should have been subtracted.
The solution should look like this:
X + 4 = 28
From each side, subtract 4 :
<em>X = 24</em>
