Find the area for the given circle with a diameter of 12 feet. Round to the nearest tenth.
Area = 113.1 square feet
pi r^2 = 3.14 * 36 =113.0 ft^2
if you use 3.14159 * 36 then 113.1 ft^2
To find the area of a circle, you can use the formula:
Area = π * (radius)^2
In this case, the given diameter is 12 feet. To find the radius, divide the diameter by 2:
Radius = Diameter / 2
Radius = 12 feet / 2
Radius = 6 feet
Now, substitute the radius into the formula:
Area = π * (6 feet)^2
The value of π is approximately 3.14159. Plugging in the values:
Area = 3.14159 * (6 feet)^2
Area = 3.14159 * 36 square feet
Calculating:
Area ≈ 113.097 square feet
Rounding to the nearest tenth:
Area ≈ 113.1 square feet
Therefore, the area of the given circle with a diameter of 12 feet is approximately 113.1 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 diameter of the circle is 12 feet, we know that the radius is half of the diameter. So, the radius will be 12 / 2 = 6 feet.
Now we can calculate the area using the formula:
A = π * r^2
A = π * 6^2
A = π * 36
To get an approximate value for π, we can use the commonly rounded value of 3.14.
A ≈ 3.14 * 36
A ≈ 113.04
Rounding the area to the nearest tenth, the area of the circle with a diameter of 12 feet is approximately 113.0 square feet.
