For instance, A( 3) is the area of an equilateral triangle inscribed in circle C, A( 4) is the area of a square inscribed in circle C, and A( 5) is the area of a regular pentagon inscribed ... read this as A equals f of r.” On the other hand, we might decide to name our area function A instead of “f ,” in which case we could write A = A( r) =πr 2 .To indicate...
