Beyond the Answer

The diameter of a circle is always twice the radius. So, if Russell has a radius of 6 centimeters, you can easily find the diameter by multiplying the radius by 2. That means the diameter is 6 cm x 2 = 12 centimeters!
This simple relationship between radius and diameter holds true for all circles, no matter how large or small. Just remember, if you know one, you can find the other quickly! So next time you pick up a compass, you can impress your classmates with your circle knowledge!
