Step 1
Find the volume of a single tennis ball
we know that
The volume of a sphere is equal to
where r is the radius of the sphere
In this problem
substitute
Step 2
Find the volume of the can
we know that
the volume of the cylinder is equal to
where r is the radius of the cylinder
h is the height of the cylinder
in this problem we have
substitute
Statement
<u>case A)</u> The volume of a single tennis ball is
The statement is true
See the procedure in Step 1
<u>case B)</u> The volume of the can is
The statement is false
The volume of the can is --> see the procedure Step 2
<u>case C)</u> The empty space inside the can is
The statement is false
To find the empty space subtract the volume of three tennis ball from the volume of the can
<u>case D)</u> The volume of three tennis balls is
The statement is true
To find the volume of three tennis balls multiply the volume of a single tennis ball by three
