What is the circumference of a circle with a diameter = 4 feet? Which of the following is the best estimation for the circumference?
I apologize for overlooking the provided answer choices.
Among the given answer choices, the best estimation for the circumference of a circle with a diameter of 4 feet would be:
- 13 feet
Since the exact value is 12.56 feet, the closest option is 13 feet.
The circumference of a circle can be calculated using the formula C = πd, where d is the diameter of the circle.
Given that the diameter is 4 feet, we can substitute this value into the formula:
C = π(4) = 4π feet.
To find the best estimation for the circumference, we can approximate π to 3.14 and multiply it by 4:
C ≈ 3.14(4) = 12.56 feet.
Therefore, the best estimation for the circumference would be approximately 12.56 feet.
What is the circumference of a circle with a diameter = 4 feet? Which of the following is the best estimation for the circumference?(1 point)
The circumference of a circle with a diameter of 4 feet can be calculated using the formula C = πd, where d is the diameter of the circle.
Given that the diameter is 4 feet, we can substitute this value into the formula:
C = π(4) = 4π feet.
To find the best estimation for the circumference, we can approximate the value of π to 3.14 (a commonly used value) and multiply it by 4:
C ≈ 3.14 * 4 = 12.56 feet.
Therefore, the best estimation for the circumference is approximately 12.56 feet.

The circumference of a circle can be calculated using the formula C = πd, where d is the diameter of the circle.
Given that the diameter is 3.25 meters, we can substitute this value into the formula:
C = 3.14 * 3.25 = 10.235 meters.
Rounding to the hundredths place, the estimated circumference of the circle is approximately 10.24 meters.

The circumference of a circle can be calculated using the formula C = 2πr, where r is the radius of the circle.
Given that the radius is 2.5 feet, we can substitute this value into the formula:
C = 2 * 3.14 * 2.5 = 15.7 feet.
Rounding to the tenths place, the estimated circumference of the circle is approximately 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 π

The area of a circle can be calculated using the formula A = πr^2, where r is the radius of the circle.
Given that the radius is 12 feet, we can substitute this value into the formula:
A = 3.14 * 12^2 = 3.14 * 144 = 452.16 square feet.
Rounding to the hundredths place, the estimated area of the circle is approximately 452.16 square feet.
