Hey there Javin!

The formula the we would use is. . .


d=2r

This would mean that we would just multiply what ever is the diameter.

So, in this case, this coin has the diameter of 22, we do
(22*2) and that would give us 44. (but that is not the answer quite yet).
_____________________________________________________________

The formula of a Circle is
A= \pi r^2 We now know that the diameter is 22.So this would mean that the radius is half of this, which is 11.

Plug int he number's in the formula, 3.14*11^2 ≈ 379.94

Your correct answer would be . . .


\boxed{\boxed{379.94}}

Hope this helps.
