What we need to do is divide 18 by 8 because 18 cups of flour makes 8 loaves of bread. By using a calculator, 18/8 = 2 1/4.
You can calculate polygon area with only apothem OR side length.
apothem only
area = apothem^2 * 6 * tan (180/6)
area = 10.4^2 * 6 * 0.57735
area = 108.16 *

side length only
area = 6 * 12^2 * / 4*tan(30)
area = 864 / 4 * 0.57735
area = 864 /

If apothem and side length were given with more precision, the answers would be closer.

Then
which is a disk of radius 1, hence with area 
.
B. $624
$8 * 25 hrs = $200 a week w/out taxes taken
$200 * 4 weeks = $800 monthly w/out taxes taken
$800 * .22 = $176 of taxes per month
$800 - $176 = $624 per month
17 goes into 68 four times and goes into 51 three times.
