The area of the circle is
... A = (π/4)d² . . . . where d=10 in
The area of the square is
... A = d² . . . . . . . . where d=10 in
The amount of the square that is not in the circle is
... (1 -π/4)d² = 0.2146018d² ≈ 21.5 in² . . . for d=10 in

I took the test
Answer: " $ 9.00 " .
____________________________________________________
The original price of the each book was: " $ 9.00 " .
____________________________________________________
Let "x" = the "original price" (in "dollars").
30% of "x" = (0.30)x = (0.3)x .
"x <span>− (0.3x) = 6.30 ;
" 1x </span><span>− 0.3x = 6.30 " ;
" (0.7)x = 6.3 " ;
Divide each side of the equation by "(0.7)" ;
to isolate "x" on one side of the equation; & to solve for "x" ;
" (0.7)x / (0.7) = 6.3 / (0.7) " ;
to get:
____________________________________________________
</span>→ x = 9 (dollars)<span>
