04. The "Diameter" and "Radius" of a Circle

By now, you should be able to know that the length of the diameter (D) of a circle is twice as its radius (r). 

The relationship between the diameter and the radius of a circle is further illustrated as below: 

1. The diameter of the circle is 2 inches.

[     ]True 
[     ] False 

2. The radius of the circle is 6 inches.

[     ]True 

[     ] False 

3. The diameter of a circle is the distance from the centre or a circle to any point on the circle... 

[     ]True 

[     ] False 






4. If you place two radii end-to-end in a circle, you would have the same length as one diameter...

[     ]True 

[     ] False 


5. Every diameter is a chord, but not every chord is a diameter...

[     ]True 

[     ] False
