<span>C=2πr</span>
where:
<span>C=</span>circumference
<span>r=</span>radius
To find the circumference, substitute your known values into the equation:
<span>C=2πr</span>
<span>C=2π<span>(7)</span></span>
<span>C=14π</span>
<span>C≈43.98 </span>
the circumference is approximately 43.98 cm. Hope I helped!
