Question

Find the diameter of a circle with the known circumference of 314” use the formula d= C

Answer 1

The complete formula for circumference is:

$C=\pi d$

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

$314=\pi d$

Using 3.14 for pi, we get:

$314=(3.14)d$

Then solve for d:

$d=100$

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