We have to simplify this as a product of fractions. Notice that the 6 has a negative sign, therefore, the result will be negative. We have then:

therefore, the simplified result is -2
The complete formula for circumference is:

Since we know the circumference of the circle is 314 inches, we can then solve for d, the diameter:

Using 3.14 for pi, we get:

Then solve for d:

And now we know the diameter of the circle is 100 inches.
