What is the circumference of a circle with a diameter = 4 feet? Which of the following is the best estimation for the circumference?
1. 6 feet
2. 25 feet
3. 13 feet
4. 50 feet
The formula for the circumference of a circle is C = πd, where C represents the circumference and d represents the diameter of the circle.
In this case, the diameter is given as 4 feet. Plugging this value into the formula, we get C = π(4) = 4π feet.
The best estimation for the circumference among the given options is 4π or approximately 12.57 feet. Therefore, none of the options provided (1. 6 feet, 2. 25 feet, 3. 13 feet, 4. 50 feet) is the best estimation for the circumference.

My apologies for the confusion. The closest estimation for the circumference of a circle with a diameter of 4 feet among the given options is option 3. 13 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 is 4 feet, we can substitute this value into the formula:
C = π * 4 = 4π
To compare the answer options, it helps to approximate π to a more familiar value of 3.14:
C ≈ 4 * 3.14 = 12.56
Out of the given options, the best estimation for the circumference is 13 feet (option 3).
To find the circumference of a circle, you can use the formula C = πd, where C is the circumference and d is the diameter of the circle. In this case, the diameter is given as 4 feet.
So, substituting the value of the diameter into the formula, we have C = π x 4 feet.
Now, let's evaluate the options:
1. 6 feet: π x 4 feet is approximately 12.57 feet, which is greater than 6 feet.
2. 25 feet: π x 4 feet is approximately 12.57 feet, which is less than 25 feet.
3. 13 feet: π x 4 feet is approximately 12.57 feet, which is close to 13 feet.
4. 50 feet: π x 4 feet is approximately 12.57 feet, which is less than 50 feet.
Based on the results above, the best estimation for the circumference is 13 feet, option 3.
