Step-by-step explanation:

Regardless of the diameter, the radius is half the diameter. For this sphere, it is 5/2 m = 2.5 m.

__

The height of the sphere is equal to its diameter, so is 2r. The volume of a cylinder with radius r and height 2r is ...

  V = πr²h = πr²(2r) = 2πr³

The volume of a sphere with radius r is ...

  V = 4/3πr³

Then the ratio of sphere volume to cylinder volume is ...

  (4/3πr³)/(2πr³) = (4/3)/2 = 2/3

The sphere volume is 2/3 that of a cylinder with the same radius and height.
