A = pi * r^2
A = pi * 21 ^2
A = 3.14 * 21 * 21
Divide the area by 280
A = pi * 21 ^2
A = 3.14 * 21 * 21
Divide the area by 280

I'm still lost

you want price per sq. inch
That is $/in^2
so, divide the cost by the area
$280/1385in^2 = (280/1385) $/in^2 = $0.202/in^2 or 20.2 cents/in^2
In all these problems, keep track of the units. That will tell you what to divide or multiply by what.
