The correct answer is:
452.16 square feet.
To find the area of a circle, you can use the formula: Area = π * radius^2.
In this case, the radius is given as 12 feet.
Step 1: Square the radius: 12^2 = 144
Step 2: Multiply the squared radius by π. Since π is given as 3.14, calculate: 144 * 3.14 = 452.16
Step 3: Round the answer to the hundredths place. The hundredths place is the second decimal place. In this case, the answer would be 452.16 square feet.
Therefore, the correct estimate for the area of a circle with a radius of 12 feet, using 3.14 for π, is 452.16 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 of the circle.
Given that the radius is 12 feet and using the approximation of π as 3.14, you can substitute these values into the formula to find the area.
A = 3.14 * (12)^2
A = 3.14 * 144
A = 452.16 square feet
Therefore, the estimated area of the circle with a radius of 12 feet is 452.16 square feet.
