Certain circle can be represented by the following equation.
kirill115 [55]

Answer:

Center of the circle is (-9, -7)

Radius of the circle = 5 units

Step-by-step explanation:

Given question is incomplete: here is the complete question.

Certain circle can be represented by the following equation. x^2+y^2+18x+14y+105=0.

What is the center of this circle ?

What is the radius of this circle ?

Since equation of the circle has been given by the equation,

x² + y² + 18x + 14y + 105 = 0

Now we will convert this equation to the standard form of the circle.

x² + 18x + y² + 14y = -105

[x² + 2(9)x] + [y² + 2(7)x] = -105

[x² + 2(9)x + 9²] + [y² + 2(7)y + 7²] = 9² + 7² - 105

(x + 9)² + (y + 7)² = 81 + 49 - 105

(x + 9)² + (y + 7)² = 25

(x + 9)² + (y + 7)² = 5²

By comparing this equation with the standard equation of the circle → (x - h)² + (y - k)² = r²

Center of the circle is (-9, -7) and radius of the circle is 5 units.

Find the area of the rug. DO NOT ROUND.<br><br> what is the area?
Mademuasel [1]

Answer:

\frac{198}{7} \ \text{feet}^{2}

<h3>Step-by-step explanation:</h3>

<u>Given:</u>

  • Diameter of rug = 6 feet

To find the area of the rug, we need to use the formula "πr² or π(D/2)²"

<u>Where:</u>

  • r = radius
  • d = diameter

Since we do not have the radius, we need to substitute the diameter in the formula "π(D/2)²" to determine the area of the rug.

⇒ \pi (\frac{D}{2} )^{2}

⇒ \pi (\frac{6}{2} )^{2}

⇒ \pi (3 )^{2}

⇒ \pi (3 )(3)

⇒ 9\pi

Substituting "22/7" as π:

⇒ 9(\frac{22}{7} )

⇒ (\frac{198}{7} )

When finding the area of ANY shape, do not forget to include the units.

⇒ \frac{198}{7} \ \text{feet}^{2}
