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)
The area of a circle is given by the formula A = πr^2, where r is the radius of the circle.
Substituting the given radius of 12 feet into the formula:
A = 3.14 * (12)^2
Calculating:
A = 3.14 * 144 = 452.16
Therefore, the area of the circle is approximately 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. In this case, the radius is given as 12 feet.
So, to find the area, substitute the given value of radius into the formula:
A = π * (12 feet)^2
Simplifying this equation:
A = π * 144 square feet
Now, to estimate the area to the hundredths place using 3.14 for π, multiply 144 by 3.14:
A ≈ 144 * 3.14
A ≈ 452.16
Therefore, the estimated area of the circle with a radius of 12 feet is approximately 452.16 square feet.
To find the area of a circle, you can use the formula A = π * r^2, where A is the area and r is the radius.
Given that the radius is 12 feet and π is estimated as 3.14, we can substitute the values into the formula:
A = 3.14 * (12 feet)^2
Simplifying the equation:
A = 3.14 * 144 square feet
Calculating the value:
A ≈ 452.16 square feet
Therefore, the estimated area of a circle with a radius of 12 feet, rounded to the hundredths place, is approximately 452.16 square feet.
