ANSWER

30 in.

EXPLANATION

The formula for calculating the circumference of a circle in terms of diameter is

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

It was given to us that the circumference is C=30π in.

We substitute this into the formula to obtain;

[tex]30\pi= \pi \: d[/tex]

Divide both sides by π to get,

[tex]30 = d[/tex]

The diameter is 30 in.

The second choice is correct.

Answer:

30 is the answer. Thank you brainly for helping me even when I have questions!    :)
