Answer 1

Answer:

30 inches

Step-by-step explanation:

The circumference of a circle can be found by using 2$\pi$r, or $\pi$ * d.

Since we are given the circumference of the circle, 30$\pi$, you can find the diameter by solving for the diameter (after substituting in the circumference) in the formula for circumference.

$30\pi =\pi *d$

To cancel out $\pi$ you can divide both sides of the equation by pi. Now you have:

30 = d

Therefore the diameter of the circle is 30 inches.
