Question

The 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?

Answer 1

12cm

Explanation:

The question is telling the ratio of radius:diameter is 1:2. This means that to get the diameter from the radius, you must multiply by 2 (and divide the diameter by 2 to find the radius).

Therefore:

6 * 2 = 12cm

Answer 2

12 bc 6/12 equals 1/2
