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 \(d=2(13)\)
