Question

the diameter of a circle measures 24 mm. what is the circumference of the circle? use 3.14 for π, and do not round your answer. be sure to include the correct unit in your answer. (there is a circle with diameter labeled 24 mm, and a text box for answer input with unit options and buttons.)

Explanation:

Step1: Find radius from diameter

The diameter $d=24$ mm, radius $r=\frac{d}{2}=\frac{24}{2}=12$ mm

Step2: Apply circumference formula

Circumference $C=2\pi r$, use $\pi=3.14$
$C=2\times3.14\times12$

Step3: Calculate the result

$2\times3.14=6.28$; $6.28\times12=75.36$

Answer:

75.36 mm
