The correct answer is: 452.16 square feet
To calculate the area of a circle, you can use the formula A = πr^2, where A represents the area and r represents the radius of the circle.
Given that the radius of the circle is 12 feet and the value of π is 3.14, you can substitute these values into the formula:
A = 3.14 * (12 feet)^2
A = 3.14 * 144 square feet
A ≈ 452.16 square feet
Therefore, the estimated area of the circle is 452.16 square feet, rounded to the hundredths place.
To find the area of a circle, you can use the formula A = πr², where A represents the area and r represents the radius.
In this case, the radius of the circle is given as 12 feet.
To estimate the area to the hundredths place using 3.14 for π, you need to substitute the values into the formula and perform the calculations.
First, square the radius: 12² = 144.
Next, multiply this result by π: 144 * 3.14 = 452.16.
Therefore, the estimated area of the circle with a radius of 12 feet is 452.16 square feet.
