The volume of a cylinder is 96 cubic meters and the height is 6 meters find the length of the diameter of this cylinder

By definition, the volume of the cylinder is:
 V = (pi) * (r ^ 2) * (h)
 Where,
 r: Radio
 h: height
 We write the equation in function to the diameter:
 V = (pi) * ((d / 2) ^ 2) * (h)
 Rewriting:
 V = (1/4) * (pi) * (d ^ 2) * (h)
 Clearing the diameter:
 d = root ((4 * V) / (pi * h))
 Substituting values:
 d = root ((4 * 96) / (3.14 * 6))
 d = 4.5 meters
 
 The length of the diameter of this cylinder is:
 d = 4.5 meters
