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) Responses
1. 13 feet
2. 10.21 meters
3. 15.7 feet
4. 452.16 square feet
5. 78.5 square mm
A. 8 feet
B. 12 feet
C. 16 feet
D. 20 feet
The best estimation for the circumference would be D. 20 feet.
To find the circumference of a circle, you can use the formula C = πd, where C is the circumference and d is the diameter.
Given that the diameter of the circle is 4 feet, we can substitute this value into the formula:
C = π * 4 = 4π feet
Now, to estimate the value of the circumference, we can use the approximation that π is approximately equal to 3.14.
Therefore, the best estimation for the circumference is 4π, which is approximately equal to 12.56 feet.

To find the circumference of a circle, you can use the formula C = πd, where C is the circumference and d is the diameter.
Given that the diameter of the circle is 4 feet, we can substitute this value into the formula:

Now, to estimate the value of the circumference, we can use the approximation that π is approximately equal to 3.14.
Therefore, the best estimation for the circumference is 4π, which is approximately equal to 12.56 feet.
None of the options provided (6 feet, 50 feet, 13 feet, 25 feet) are the best estimation for the circumference.
To find the circumference of a circle, we can use the formula: C = πd, where C is the circumference and d is the diameter.
In this case, the diameter of the circle is given as 4 feet. So, we can substitute this value into the formula:
C = π * 4
C ≈ 12.57 feet
Now, let's consider the options given:
1. 25 feet
2. 10 feet
3. 12.57 feet
4. 5 feet
The best estimation for the circumference would be option 3, 12.57 feet, as it closely matches the calculated value.
