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.
