Answer:
30 inches
Step-by-step explanation:
The circumference of a circle can be found by using 2r, or
* d.
Since we are given the circumference of the circle, 30, you can find the diameter by solving for the diameter (after substituting in the circumference) in the formula for circumference.
To cancel out you can divide both sides of the equation by pi. Now you have:
30 = d
Therefore the diameter of the circle is 30 inches.
