Which measurements for the capacity of the ice cream carton?

nalin [4]

Answer:

1 cup
1 gallon

Step-by-step explanation:

In retail grocery stores in the US, you can find ice cream packaged in sizes of 1 cup (half pint), 1 pint, 1 quart, 1/2 gallon, 1 gallon, and perhaps some odd sizes in between. For commercial purposes, ice cream may be packaged in tubs of 3- or 5-gallons or more.

1 teaspoon would be an unusually small size, and 1 mL is about 1/5 of a teaspoon. These quantities are somewhat smaller than would be considered a "serving" of ice cream, so would generally be of little practical use.

To find the lateral area you use the equation

$\pi r \sqrt{ h^{2} + r^{2} }$

You put in the values you know and you get 829.4

To find the surface area you use the equation

$\pi r(r+ \sqrt{ h^{2} + r^{2} }$

Put in the values you know and you get 1209.5
