Answer 2

Answer:

a. Irrational

Step-by-step explanation:

Radius of the circle = 7 cm

Circumference of circle = 2*π*r

                                        = 2*22/7*49

                                        = 2*22*7

                                        = 44*7

                                        = 308 cm

Because 308 is not a perfect square number so, it is irrational.
