Question

what is its circumference? use 3.14 for π, and do not round your answer. be sure to include the correct unit in your answer. (a circle with radius 4 ft is shown)

Explanation:

Step1: Recall circumference formula

The formula for the circumference of a circle is $C = 2\pi r$, where $r$ is the radius.

Step2: Substitute given values

Here, $r = 4$ ft and $\pi = 3.14$. Substitute into the formula:
$C = 2 \times 3.14 \times 4$

Step3: Calculate the result

First compute $2 \times 4 = 8$, then $8 \times 3.14 = 25.12$. The unit is feet (ft) since circumference is a linear measurement.

Answer:

25.12 ft
