A flower pot has a diameter of 6 feet. What is the area of the flower pot, to the nearest whole number?
Elodia [21]

Answer:

28 ft²

Step-by-step explanation:

The area of a circle is \pi r^2, where r = radius. To find the radius, we split the diameter in half.

  • 6/2 = 3
  • Thus, the radius is 3.

Now, let's find the area of the circle and approximate pi to 3.14.

  • 3.14*3^2
  • 3.14*9
  • 28.26
  • 28.26 ≈ 28 ft²

Therefore, the answer is 28 ft².
