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)
50 feet
13 feet
25 feet
6 feet
The circumference of a circle can be calculated using 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 to find the circumference:
C = π(4) = 4π
Using an approximation of π ≈ 3.14, we can estimate the circumference:
C ≈ 4 * 3.14 ≈ 12.56
Among the given options, the best estimation for the circumference is 13 feet, as it is the closest value to the calculated approximation of 12.56 feet.
To find the circumference of a circle, you can use the formula C = πd, where C represents the circumference and d represents the diameter. In this case, the diameter is given as 4 feet.
So, the circumference can be calculated as C = π × 4 feet.
Now, let's evaluate the given answer options to determine the best estimation for the circumference.
- 50 feet: This value is significantly larger than the circumference calculated above.
- 13 feet: This value is considerably smaller than the circumference calculated above.
- 25 feet: This value is closer to the circumference calculated above.
Therefore, the best estimation for the circumference of a circle with a diameter of 4 feet is 25 feet.
To find the circumference of a circle, you need to know the diameter. The circumference of a circle is calculated using the formula: circumference = π * diameter, where π is a mathematical constant approximately equal to 3.14.
In this case, the diameter is given as 4 feet. So, we can plug this value into the formula to find the circumference:
circumference = 3.14 * 4 = 12.56 feet (approximately)
Therefore, the best estimation for the circumference of this circle is 13 feet, as it is the closest to the calculated value of 12.56 feet.
