Question

Ice cream is packaged in cylindrical gallon tubs. A tub of ice cream has a total surface area of 183.69 square inches.

If the diameter of the tub is 6 inches, what is its height? Use π = 3.14.

A 2.25 inches
B 4.5 inches
C 6.75 inches
D 12.75 inches

Answer 1

6.75 inches.

Explanation:

`183.69 = 2*3.14*3^2 + 2*3.14*3*h`

`= 56.52 + 18.84h`

`183.69 - 56.52 = 18.84h`

`127.17 = 18.84h`

`=(127.17)/(18.84)`

`=6.75`
