Expert Answer:

V a l u e space o f space straight pi space equals 3.141592653589793..... Thus comma space the space decimal space numbers space after space the space decimal space point space are space non minus repeating space and space non minus terminating. Therefore comma space straight pi space is space an space irrational space number. Consider space the space rational space number space 22 over 7 Since space it space is space of space the space form space straight p over straight q comma space where space straight q not equal to 0 comma space 22 over 7 space is space straight a space rational space number. space But space straight pi almost equal to 22 over 7 space is space an space approximation space only.
