Question

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

Answer 1

$\bf \begin{array}{ccllll} population&radius\\ -----&-----\\ 19465000&5\\ 25675000&t \end{array}\implies \cfrac{19465000}{25675000}=\cfrac{5}{t}\impliedby texas \\\\\\ \begin{array}{ccllll} population&radius\\ -----&-----\\ 19465000&5\\ 37691000&c \end{array}\implies \cfrac{19465000}{37691000}=\cfrac{5}{c}\impliedby california$

solve for "t" and "c" respectively
