Answer:

b. 1.2 in

Step-by-step explanation:

The formula of a circumference:

[tex]C=d\pi[/tex]

d - diameter

We have C = 3.75 in.

Substitute:

[tex]d\pi=3.75\qquad\text{use}\ \pi\approx3.14\\\\3.14d=3.75\qquad\text{divide both sides by 3.14}\\\\d=\dfrac{3.75}{3.14}\\\\d=\dfrac{375}{314}\\\\d\approx1.2\ in[/tex]
