You need to multiply pi by the radius (half the diameter/12) squared to find the area!
For this case we have that by definition, the general equation of the circle is given by:
Where,
- <em>(h, k): it is the center of the circle
</em>
- <em>r: radius of the circle
</em>
We then have the following equation:
Comparing values we have:
For the center of the circle
:
For the radius:
Then, the diameter is given by:
Answer:
Johnny is wrong:
The center of the circle is (11, -15)
Joyce is wrong:
The diameter of the circle is 24
Answer: you need to show the rest because i dont know. four times what?
