a can of tennis balls consists of three spheres stacked vertically inside a cylinder the balls just Touch the top, bottom, and sides of the cylinder. A diameter of each ball is 6.67 cm. find The Following. use 3.14 for pie and round to the nearest hundredth

1 answer

height of one ball is 6.67 (its diameter)
height of 3 balls is therefore 20cm

if you want volume of all 3 balls, that'd be 3(1/6 πd^3)
where d is the diameter.

volume of cylinder is just
πr^2 h = π/4 d^2 h = 3π/4 d^3 = 3π/4 (20/3)^3 = 200π/9

Or maybe something else, since you didn't ask a question.
