Question

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

Answer 1

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.
