Question

a circle has a radius of 3 ft. what is its circumference? use 3.14 for $pi$, and do not round your answer. be sure to include the correct unit in your answer.

Explanation:

Step1: Recall the circumference formula

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

Step2: Substitute the given values

Given $r = 3$ ft and $\pi=3.14$, we substitute into the formula: $C=2\times3.14\times3$.

Step3: Calculate the result

$C = 18.84$ ft.

Answer:

$18.84$ ft
