[4 pts) Determine the size of the following sets. If the set is infinite, determine if it's countably or uncountably infinite. (a) A = {(x, y) E R2 : x2 + y2 = 1} (b) B = {(x,y) € R2 : x2 + y2 <1} (c) C = {1,1.4, 1.41, 1.414, 1.4142, ...}, i.e., each element is a successively better approximation of V2 (d) D = {all 5 digit natural numbers}
