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}
