QuestionThe ratio of a circle's radius to its diameter is always 1 to 2 . In math class, Russell uses his compass to draw a circle with a radius of 6 centimeters.
What is the diameter of the circle Russell drew? \square centimeters

Studdy Solution
Use the relationship to find the diameter:
Given that the radius r=6r = 6 cm, substitute into the formula:
d=2×6 cm d = 2 \times 6 \text{ cm}
Calculate the diameter:
d=12 cm d = 12 \text{ cm}
The diameter of the circle Russell drew is:
12 cm \boxed{12 \text{ cm}}
