Question

Find the area of the rug. DO NOT ROUND.

Answer 1

28.26 feet²

Explanation:

Substitute the radius in the formula:

⇒ Area of circular rug = πr²

⇒ Area of circular rug = π(6/2)² [Diameter/2 = Radius]

Simplify the R.H.S:

⇒ Area of circular rug = π(3)²

⇒ Area of circular rug = π(9) [(3)² = 3 × 3 = 9]

Take π as 3.14 and simplify:

⇒ Area of circular rug = (3.14)(9)

⇒ Area of circular rug = 28.26 feet² (Using calculator)

Answer 2

28.26 ft²

Explanation:

Formula

• Area = πr²

Given :

• Diameter = 6 ft
• ⇒ Radius = 3 ft [Diameter = 2 x Radius]

Solving :

• Area = 3.14 x 3 x 3
• Area = 3.14 x 9
• Area = 28.26 ft²
