You are planning on using circles to compare the populations of california 37,691,000, texas 25,675,000, and new york 19,465,000. if the circle for new york will have a 5 cm radius, how large should the radii for texas and california be? round to the nearest tenth of cm.

The question above may be answered through the concept of ratio and proportion. The ratio between the population of a certain city and the radius of the circle used should be proportional. Mathematically, 
                             19465000/5 = 37691000/x₁ = 25,675,000/x₂
The values of x₁ and x₂ are 9.7 cm and 6.6 cm, respectively. 

You can use a calculater and divide the minutes by the $$, hope that you
