toy rubber balls are packaged in a circular cylinder that holds 3 balds. the diameter of each ball is 3.7 cm find the volume of the circular cylender use 3.14 to represent

isn't the height equal to 3 diameters?
volume = π(r^2)(h)
Tennis balls used to be sold in metal cans to hold exactly 3 tennis balls.
I used to hold up the can and challenge my students to tell me with only mental calculations which was greater,
the height of the can or the circumference of the can?
