Question

Hank pours himself a jar full of

milk to drink with his pie. The jar is 6"
high and 3" in diameter. What is
the volume of the jar?

Answer 1

13.5pi inches^3

Explanation:

the jar is a cylinder.

the volume of a cylinder is the height * base area, and the base area is a circle. the area of a circle is pi*r^2.

the radius is half the diameter, so it is 1.5.

the area of the circle is pi * 1.5^2 = 2.25pi.

multiply this by the height, and we get 13.5pi. the units is cubic inches, or inches^3.
