So our equation currently is ⇒
<u>Let's first move all the constant to one side and group 'like variables' together</u>:
<u>Now lets complete the square of both equations</u>
<u><em>Now we know the circle's general equation format is</em></u>:
⇒
- (h, k) ⇒ coordinate of the center of the circle
- r ⇒ length of radius of circle
<u>Thus the radius of the circle is 7</u>

Answer:
Step-by-step explanation:
Given
Required
Complete the model
[ ] x = 6.60
x = _ hundredths
Equate to x
Multiply both sides by 15
So, we have:
[ ] x = 6.60 =====>
Recall that:
This implies that:
Hence:
x = _ hundredths =====>
