Complete Solution:
To determine an answer mathematically, find
the volume of
each cylinder. The volume is the area
of the base times
the height. In this case, the bases are circular.
The area
of a circle is
×
r ×
r or approximately 3.14
×
r ×
r. To find the radius,
r, use a ruler to
estimate the width (or diameter) of the circle. Divide
the diameter by 2 to get the radius.
Another way to find the radius
of a circle is to use the formula:
Circumference = 2 ×
×
radius = 2r.
Radius = Circumference ÷
(2 ).
Once you have the radius, the table below shows how to
determine the volume of each cylinder. The sheet of paper
is 8 1/2 inches by 11 inches.
The volume
of the shorter cylinder
is about 82 cubic
inches, and the volume
of the taller cylinder
is about 63 cubic inches.
