4x² + 18x + 18
Answer: 20
Step-by-step explanation:
a^2+b^2=c^2 (pythagorean theorem where c is hypotenuse)
12^2+16^2=c^2
144+256=c^2
400=c^2
square root of 400=20
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
