What is the area of a circle with a radius of 12 feet? Estimate the area to the hundredths place using 3.14 for π.(1 point).(1 point)
452.2ft
452.16ft
113.04ft
75.4ft
The area of a circle is calculated using 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. Plugging this value into the formula, we get:
A = 3.14 * 12^2
A ≈ 3.14 * 144
A ≈ 452.16
Therefore, the estimated area of the circle is 452.16 square feet. The correct answer is 452.16ft².
To find the area of a circle, you can use the formula A = π * r^2, where A is the area, π (pi) is a mathematical constant approximately equal to 3.14, and r is the radius of the circle.
Given that the radius of the circle is 12 feet, you can substitute this value into the formula:
A = 3.14 * 12^2
A = 3.14 * 144
A = 452.16
Therefore, the area of the circle with a radius of 12 feet is approximately 452.16 square feet.
