Hello from MrBillDoesMath!
Volume of a cylinder of height "h" and radius "r is given by the formula
Pi * r^2 * h
(Think of this are pushing the area of the circle or radius r up through a distance h)
In our case this equals
Pi * 2^2 * 7 =
Pi * 4 * 7 =
Let x= number of cases
You will need 2 cases of soap every day.
To figure out how many cases you would need in a week:
You would need 14 soap cases in a week.
Hope this helps!
-7k⁵(-5k⁴ + 2) = -7k⁵(-5k⁴) - 7k⁵(2) = 35k⁹ - 14k⁵
