The diameter of the larger circle is 10.5 cm. the diameter of the smaller circle is 4.5 cm. what is the best approximation for the area of the shaded region? use 3.14 to approximate pi. 70.7 cm² 86.5 cm² 102.4 cm² 282.6 cm² small circle inside big circle, shaded region outside smaller circle and inside larger circle.

The customer price index(cpi), which measures the cost of a typical package of customer goods,was 208.8 in 2011 and 244.1 in 2016.let x=11 corresponding to the year 2011 an estimate to cpi into 2013 and 2014. assume that the data can be modeled by a straight line and the trend to continue idenfinitely.use data points to find such a line and then estimate the requested quantities
