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
O 25 feet
O 6 feet
The circumference of a circle can be found using the formula C = πd, where d is the diameter of the circle.
In this case, the diameter is given as 4 feet.
Using the formula, we get C = π(4) = 4π feet.
Since π is approximately 3.14, the best estimation for the circumference is 4(3.14) = 12.56 feet.
Therefore, none of the given options (50 feet, 13 feet, 25 feet, 6 feet) are the best estimation for the circumference.
To find the circumference of a circle, you can use the formula:
Circumference = π x diameter
Given that the diameter of the circle is 4 feet, we can substitute this value into the formula:
Circumference = π x 4
Now, to estimate the value of π, we can use the approximate value of 3.14.
So, the estimated circumference of the circle would be:
Circumference = 3.14 x 4 = 12.56 feet
Looking at the given options, the best estimation for the circumference is 13 feet.
To find the circumference of a circle, you can use the formula:
Circumference = π × Diameter
Given that the diameter of the circle is 4 feet, we can substitute this value into the formula:
Circumference = π × 4 feet
Now, to determine the best estimation for the circumference, we need to evaluate the options provided.
Let's calculate the circumference using π (pi) as an approximation of 3.14:
Circumference ≈ 3.14 × 4 feet
Circumference ≈ 12.56 feet
Now, let's compare this estimated value to the given options:
- Option 1: 50 feet - This value is significantly greater than the estimated circumference of 12.56 feet.
- Option 2: 13 feet - This value is slightly larger than the estimated circumference of 12.56 feet.
- Option 3: 25 feet - This value is significantly greater than the estimated circumference of 12.56 feet.
- Option 4: 6 feet - This value is smaller than the estimated circumference of 12.56 feet.
Based on the comparison, the best estimation for the circumference of the circle with a diameter of 4 feet is 12.56 feet.
