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. a. What is the volume of the cylinder? Explain your method for finding the volume. b. What is the total volume of the three balls? Explain your method for finding the total volume. c. What percent of the volume of the container is occupied by the three balls? Explain how you would find the percent. Ok, so I just need my answer checked. I'll post the image and answer in the comments.

    A) Volume of a cylinder is pi*r^2*h. So, pi*6.5*6.5*39=5176cm^3. B) Volume of 3 balls is 3(4/3 pi*r^3) So, 4*pi*6.5*6.5*6.5=3451cm^3. C) 3451/5176*100=66.66%
