The problem was "Three balls are packaged in a cylindrical container as shown below. The balls just touch the top, bottom, and sides of the cylinder. The diameter of each ball is 13 cm." I'm just having trouble with it.

oops forgot the additional prompts

anonymous · Answer

for a) multiply the diametre with pi. then multiply the answer with the height of the cyliner which would be the length of three diametres.

anonymous · Answer

for b) cube the radius of one tennis ball. then multiply that with (4/3) and then multiply by pi. once you have done that multiply every thing by 3 as there are three tennis balls.
