804.24 - we know this because the area of a circle is r^2*pi. If we double the radius we get (2r)^2*pi or 4r^2*pi. We notice that this is just 4 times the area of the original circle, equating to 804.24.
Answer:
this is the formula for area of a trapezoid
Answer:
Therefore the most Marney can pay for a case of 20 soda bottles is = $ 25.344

Therefore the most Marney can pay for a case of 20 soda bottles is = $ 25.344
20 cartons
total of eggs = 20x12=240
240------ 100%
60------ x %
x is the percentage that represents 60 cracked eggs
![x=\frac{60\cdot100}{240}=25](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B60%5Ccdot100%7D%7B240%7D%3D25)
The percent of the eggs are cracked is 25%
