Diameter is 2.36 cm.
Given:
Circumference = 7.38 cm
Circumference of a circle is computed by multiplying 2, pi, and its radius.
C = 2πr
7.38 = 2 (3.14) r
7.38 = 6.28r
7.38/6.28 = 6.28r/6.28
1.18 = radius
Diameter = 2r
Diameter = 2(1.18)
Diameter = 2.36 cm
Basically the remainder theorem links the remainder of division by a binomial with the value of a function at a point while the factor theorem links the factors of polynomial to its zeros
Please, see the offered solution, note, there are 2 ways in it (a and b)
7x+7b = 7(x+b)
