If you have a circular flower bed that has a diameter of 18 feet. How many square feet of the yard is covered by the flower bed? help please !

A = pi * r^2

A = 3.14 * 9^2

A = 3.14 * 81

A = _____ square feet

To find the area of the flower bed, we need to use the formula for the area of a circle: A = πr², where A represents the area and r represents the radius of the circle.

Given that the flower bed has a diameter of 18 feet, we can find the radius by dividing the diameter by 2. So the radius (r) would be 18/2 = 9 feet.

Now, we can calculate the area of the flower bed by substituting the radius into the formula. Using the value of π as approximately 3.14159, we have:

A = 3.14159 × (9)²
≈ 3.14159 × 81
≈ 254.469 square feet.

Therefore, the flower bed covers approximately 254.469 square feet of the yard.
