Match the values in this circle to those of the standard form. The variable
r
represents the radius of the circle,
h
represents the x-offset from the origin, and
k
represents the y-offset from origin.
r
=
8
h
=
−
4
k
=
7
The center of the circle is found at
(
h
,
k
)
.
Center:
(

)
These values represent the important values for graphing and analyzing a circle.

Step-by-step explanation:
Answer:
The answer is 21
Step-by-step explanation:
The answer is 21 because...
- <em>It is hard to explain but for step one you need to take the dotted line and the shape above hat and move it underneath the other shape to make a perfect rectangle.</em>
- <em>Step two since the dotted line is our new bottom. It has a length of 7. In this step we multiply 3 times 7 </em>
- <em>Step 3 this is the final step in which 3 times 7 equals 21.</em>
- <em>Hope this helped :)</em>
