To find the area of a circle, you use the formula A = πr^2, where A is the area and r is the radius. Since the radius is given as 12 feet, we can plug this value 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, which is closest to the option 452.2 square feet.
To find the area of a circle, you can use the formula A = πr^2, where A represents the area and r represents the radius.
In this case, the radius is given as 12 feet.
Substituting this value into the formula, we get A = 3.14 * (12)^2.
Evaluating this expression, we find A = 3.14 * 144 = 452.16.
Rounded to the hundredths place, the estimated area of the circle is 452.16 square feet.
