The circumference of circle is defined by: C = pi * diameter, and this case:
A = pi * d = around 3.14*d
B = 2d*2 + d*2 = 6d
so if d is non-negative B always is greater than A. Answer is B.
A = pi * d = around 3.14*d
B = 2d*2 + d*2 = 6d
so if d is non-negative B always is greater than A. Answer is B.
