The circumference of a circle can be calculated using the formula C = πd, where C is the circumference and d is the diameter. In this case, the diameter is given as 4 feet.
Using the formula, we can calculate the circumference C = π(4) = 4π feet.
Among the given options, the best estimation for the circumference would be 13 feet, as 4π is approximately equal to 12.57, which rounds to 13.
The formula to calculate the circumference of a circle is C = π * d, where C is the circumference and d is the diameter. In this case, the diameter is given as 4 feet.
To calculate the circumference, we substitute the value of the diameter into the formula:
C = π * 4 feet
C ≈ 3.14 * 4 feet
C ≈ 12.56 feet
Therefore, the best estimation for the circumference of a circle with a diameter of 4 feet is 12 feet.
To calculate the circumference of a circle, you can use the formula: C = πd, where C represents the circumference and d is the diameter of the circle. In this case, the diameter is given as 4 feet.
So, the circumference (C) is equal to π times the diameter (d).
C = π * d
C = π * 4
To find the best estimation for the circumference, we need to evaluate the options provided:
Option 1: 50 feet
Option 2: 25 feet
Option 3: 6 feet
Option 4: 13 feet
To determine the best estimation, we need to compare the calculated circumference value to the options given.
C ≈ 3.14 * 4
C ≈ 12.56 feet
Among the provided options, the best estimation for the circumference would be 13 feet since it is the closest value to the calculated circumference of approximately 12.56 feet.

The circumference of a circle can be calculated using the formula C = πd, where C is the circumference and d is the diameter. In this case, the diameter is given as 3.25 meters.
Using the formula, we can calculate the circumference C = 3.14 * 3.25 = 10.205 meters.
Among the given options, the best estimation for the circumference would be 10.21 meters, as it is the closest value to the calculated circumference of 10.205 meters when rounded to the hundredths place.
