Answer:
<h2>Yes the circumference is about times greater than their diameters</h2>
Step-by-step explanation:
We will approach this problem by doing a check
Say the diameter of a circle is 4 cm
Hence the radius is 3 cm
We know that the circumference is ![C=2\pi r](https://tex.z-dn.net/?f=C%3D2%5Cpi%20r)
![C=2*3.142*2= 12.57cm](https://tex.z-dn.net/?f=C%3D2%2A3.142%2A2%3D%2012.57cm)
The circumference is about 3 time bigger than the diameter
Let us try another case say the diameter is 6 cm
The radius is 3 cm
![C=2*3.142*3= 18.85cm](https://tex.z-dn.net/?f=C%3D2%2A3.142%2A3%3D%2018.85cm)
