She would've eaten half of the cake, or 8 oz.
The answer is 5/9. I showed a bit more work on the other post
Volume of a cylinder= πr²h.
So pi always =3.14.
The radius is half the diameter: 20/2=10.
The height is the height of the flour in the canister: 25-3=22.
So V=3.14(10²)(22).
V=3.14(100)(22).
V=314(22).
V=6,908 cm³ :)
You should write a ( real world situation ) question that can only have whole numbers as a solution because you would divide and then you can not have a fraction left over so instead you add one. For instance there are 132 students going on a field trip. 20 students can fit on each bus. how many buses are needed? 7 because when you divide 132 by 20 you get 6 remainder 12. You can not just make 12 students walk to the location so you would add an extra bus.
