Classify each polynomial and determine its degree.

No picture was included

The sector shown is 1/8 of the pie, so its area will be
   A = (1/8)*π*r²
   = (1/8)*π*(7.5 ft)²
   = 7.03125π ft²
   ≈ 22.08932... ft²

Given the available choices, the appropriate selection is probably
   a. 22.08 ft²


The real answer is not among those offered. It should be 22.09 ft².
