A has a diameter and a height of 8 inches each. Let's start by drawing it.
The volume of a cylinder with the radius
r and height
h can be calculated by the following formula.
V=πr2h
Since the
d is
8, we can find the radius by dividing the diameter by
2.
Now, we can substitute them into the formula and calculate
V.
V=πr2h
V=π(4)2(8)
V=π(16)(8)
V=π(128)
V=402.123860…
V≈402.1
The volume of the given cylinder is about
402.1 cubic inches.
