45 pages total 3 on last page 45-3=42 there are 42 on the rest of the pages on each page, there are 2 more pages in album than then stamps on pages
amount of stamps on pages with equal number of stamps is A=numberofpgest times number of stamps on pages number of pages=p number of stamps per papge=s a=ps
2 more pages than stamps on pages p=2+s total number of stamps per page is s=(45-3)/(p-1) (what I did is I first got rid of number of stamps on last page, then got rid of the last page) P=2+s s=(45-3)/(2+s-1) s=42/(s+1) times s+1 both sides s^2+s=42 minus 42 s^2+s-42=0 factor (s-6)(s+7)=0 set equal to zero s-6=0 s=6
So it gives you the diameter but you need the radius of the circle to find the area so to find the radius you just divide the diameter by two. the formula for the area of a circle is A=pi*r^2 so you just multiply 3.14 by 3 squared so you just put it in the calculator as A=3.14*3^2 and you get 28.26 hope this helped
