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)
• 25 feet
• 6 feet
• 13 feet
• 50 feet
The circumference of a circle is given by the formula: C = πd, where d is the diameter of the circle.
Given that the diameter is 4 feet, we can calculate the circumference:
C = π(4) = 4π ≈ 12.57 feet
Therefore, the best estimation for the circumference is approximately 13 feet.
