Step-by-step explanation:
Set up a proportion comparing like things.
It's easier to see if you write the small triangle separately.
See image.
I've done the calculation twice. Just look at the one that makes the most sense to you Obviously, it works out the same either way.
The formula for this is

. If the diameter is 8 the radius is 4, so filling in accordingly we have

and

which is

and when you multiply in 3.14 you get that A = 401.92 or B above.
