Answer 2

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.
