what is the circumference of a circle with a diameter of 12 ft? estimate the area to the hundredths place using 3.14
To find the circumference of a circle, you can use the formula:
Circumference = π * diameter
Given that the diameter of the circle is 12 ft, we can substitute this value into the formula:
Circumference = 3.14 * 12
Circumference = 37.68 ft (rounded to two decimal places)
Therefore, the circumference of the circle with a diameter of 12 ft is approximately 37.68 ft.
As for the estimated area, you asked for an estimate to the hundredths place using the value of π as 3.14. The formula for calculating the area of a circle is:
Area = π * radius^2
Since the diameter is given, we can calculate the radius by dividing the diameter by 2:
Radius = diameter / 2
Radius = 12 ft / 2
Radius = 6 ft
Now we can substitute the radius value into the formula:
Area = 3.14 * (6 ft)^2
Area = 3.14 * 36 ft^2
Area = 113.04 ft^2 (rounded to two decimal places)
Therefore, the estimated area of the circle with a diameter of 12 ft is approximately 113.04 square feet.
To find the circumference of a circle, you can use the formula:
Circumference = Diameter × π
Given that the diameter of the circle is 12 ft and you want to use an approximation of π as 3.14, you can calculate the circumference as follows:
Circumference = 12 ft × 3.14
Circumference = 37.68 ft
Therefore, the circumference of the circle with a diameter of 12 ft is approximately 37.68 ft.
To estimate the area of the circle using an approximation of π as 3.14, you can use the formula:
Area = π × (radius)^2
Since the diameter is given, you can find the radius by dividing the diameter by 2:
Radius = 12 ft ÷ 2
Radius = 6 ft
Now, use the radius to calculate the estimated area:
Area = 3.14 × (6 ft)^2
Area = 3.14 × 36 ft^2
Area ≈ 113.04 ft^2
Therefore, the estimated area of the circle is approximately 113.04 square feet, rounded to the hundredths place.
To find the circumference of a circle, you can use the formula:
C = πd
Given that the diameter (d) is 12 ft, we can estimate the circumference using π ≈ 3.14:
C = 3.14 * 12
C ≈ 37.68 ft
The circumference of the circle with a diameter of 12 ft is approximately 37.68 ft.
To estimate the area of the circle, you can use the formula:
A = πr^2
Since we know the diameter is 12 ft, we can find the radius (r) by dividing the diameter by 2:
r = 12 / 2
r = 6 ft
Now we can calculate the area using π ≈ 3.14:
A = 3.14 * 6^2
A ≈ 3.14 * 36
A ≈ 113.04 sq ft
Therefore, the estimated area of the circle to the hundredths place is approximately 113.04 sq ft.
