an equation of a circle is x2 + y2 + 10x – 6y + 18 = 0. . . . A.Show all your work in determining the center and radius of this
MariettaO [177]

A circle is a set of points in a plane equidistant from a fixed point. It has a general formula of x² + y² = r². This is if the center is at the origin. However, if the center at point h and k, the equation becomes (x-h)² + (y-k)² = r².<span>

We write the given equation in the form (x-h)² + (y-k)² = r² by completing the square.
</span>

<span>x</span>²<span> + y</span>²<span> + 10x – 6y + 18 = 0</span>

<span> (x² + 10x + 25 )+ (y² - 6y + 9) = −18 + 25 + 9 = 16
(x + 5)² + (y + 3)² = (4)²

Therefore,

center = (-5, -5)
radius = 4</span>

Can y’all help me please I need help
Illusion [34]

Answer:

503 inches (rounded to the nearest whole number)

Step-by-step explanation:

First, we must calculate the wheel's circumference, or in other words, the distance around the wheel. We can do this by using the below equation:

C=\pi d when d is the diameter

Because we know that the wheel's diameter is 16 inches, we can plug it into the equation:

C=\pi (16)\\C=16\pi

Now, because we know that the wheel makes 10 revolutions, we calculate the distance it travelled by multiplying the circumference by 10.

16\pi *10\\= 160\pi

= 503 inches when rounded to a whole number

Therefore, the wheel travelled approximately 503 inches.

I hope this helps!
