Which pitcher has a greater capacity, one that holds 2 gallons or one that holds 12 quarts? how do you know?

1 gallon is 4 quarts so just divide 12 by 4 and you get three. So the 12 quarts equals 3 gallons which is obviously bigger than 2.

Area of a Circle= (pi)(radius) squared

Find the area of each cake, then subtract the difference between those 2 answers to find the difference in area. Also remember the problem gives you diameter, but the area formula requires radius so you must divide the diameter by 2.

Vanilla Cake Area
A= (3.14)(8/2) squared
A=(3.14)(4) squared
A=(3.14)(4*4)
A=(3.14)(16)
A=50.24 inches

Chocolate Cake Area
A=(3.14)(10/2) squared
A=(3.14)(5) squared
A=(3.14)(5*5)
A=(3.14)(25)
A=78.5 inches

Difference in Area
Chocolate Area - Vanilla Area
= 78.5 - 50.24
= 28.26 inches difference

Hope this helped!! :)
