Answer:
15/2π
Step-by-step explanation:
If the circumference is 15 inches, we can create an equation using the following formula:
Circumference of circle = 2 x π x radius
which is C = 2πr
Now, substituting our value of the circumference (15) into the equation, we get:
15 = 2πr
In order to find r, the radius, we must divide both sides by 2π, which makes r the subject. This cancels out the 2π on the right side, leaving us with:
15/2π = r
So the radius is 15/2π.
