Answer: $d=2(13)$

Step-by-step explanation:

We know that, the diameter of a circle is twice of the radius of the circle.

Therefore, if r is the radius of the circle, then diameter of the circle will be :-

$d=2r$

Given: A circle has a radius of 13 inches.

Therefore, the diameter of the given circle will be :-

$d=2(13)=26\ inches$

Hence, the equation which can be used to find the diameter of this circle is $d=2(13)$
