Consider the following graph, which shows the U.S. population in 2000 and the projected U.S. population in 2050.

(a) Compute the projected percent increase in population from 2000 to 2050 by using the formula . 

(b) Measure the radius and then compute the area of the circle representing 2000. Use A = πr².

(c) Repeat part (b) for the circle representing 2050.

(d) Compute the percent increase in the size of the area of the circle from 2000 to 2050. 

(e) Are the circle graphs misleading?
