The circumference of a circle is calculated using the formula: circumference = π * diameter.
Given that the diameter is 4 feet, we can substitute this value into the formula:
circumference = π * 4 feet
Now, let's estimate the value of π as 3.14 (a common approximation):
circumference ≈ 3.14 * 4 feet
circumference ≈ 12.56 feet
Among the given options, the best estimation for the circumference is 13 feet as it is the closest value to the calculated estimation of approximately 12.56 feet.

What is the circumference of a circle with a diameter of 3.25 meters? estimate the circumference to the hundredths place using 3.14 for pi
The circumference of a circle is calculated using the formula: circumference = π * diameter.
Given that the diameter is 3.25 meters, we can substitute this value into the formula:
circumference = 3.14 * 3.25 meters
circumference = 10.21 meters
When estimating to the hundredths place, the best estimate for the circumference would be 10.21 meters.
Given that the diameter is 3.25 meters, we can substitute this value into the formula:
circumference = 3.14 * 3.25 meters
circumference = 10.21 meters
When estimating to the hundredths place, the best estimate for the circumference would be 10.21 meters.
What is the circumference of a circle with a radius of 2.5 feet estimate the circumference to the tenths place using 3.14 for pi
The circumference of a circle is calculated using the formula: circumference = 2 * π * radius.
Given that the radius is 2.5 feet, we can substitute this value into the formula:
circumference = 2 * 3.14 * 2.5 feet
circumference = 15.7 feet
When estimating to the tenths place, the best estimate for the circumference would be 15.7 feet.
Given that the radius is 2.5 feet, we can substitute this value into the formula:
circumference = 2 * 3.14 * 2.5 feet
circumference = 15.7 feet
When estimating to the tenths place, the best estimate for the circumference would be 15.7 feet.
what is the area of a circle with a radius of 12 feet estimate the area to the hundredths place using 3.14 for pi
The area of a circle is calculated using the formula: area = π * (radius)^2.
Given that the radius is 12 feet, we can substitute this value into the formula:
area = 3.14 * (12 feet)^2
area = 3.14 * (144 feet^2)
area = 452.16 square feet
When estimating to the hundredths place, the best estimate for the area would be 452.16 square feet.
Given that the radius is 12 feet, we can substitute this value into the formula:
area = 3.14 * (12 feet)^2
area = 3.14 * (144 feet^2)
area = 452.16 square feet
When estimating to the hundredths place, the best estimate for the area would be 452.16 square feet.
what is the area of a circle with a diameter of 10 millimeters estimate the area to the tenths place using 3.14 for pi
The area of a circle is calculated using the formula: area = π * (radius)^2.
Given that the diameter is 10 millimeters, we can first calculate the radius by dividing the diameter by 2:
radius = 10 millimeters / 2 = 5 millimeters
Now, we can substitute this value into the formula:
area = 3.14 * (5 millimeters)^2
area = 3.14 * 25 square millimeters
area = 78.5 square millimeters
When estimating to the tenths place, the best estimate for the area would be 78.5 square millimeters.
Given that the diameter is 10 millimeters, we can first calculate the radius by dividing the diameter by 2:
radius = 10 millimeters / 2 = 5 millimeters
Now, we can substitute this value into the formula:
area = 3.14 * (5 millimeters)^2
area = 3.14 * 25 square millimeters
area = 78.5 square millimeters
When estimating to the tenths place, the best estimate for the area would be 78.5 square millimeters.
