ONLY ANSWER IF YOU KNOW HOW TO DO THIS.

Until 2014, the mass of a kilogram was defined as exactly equal to the mass of a special platinum-iridium cylinder kept in Sèvres, France. The cylinder’s diameter and height are both 39.2 millimeters. What is the volume of this cylinder?

  1. Answer:
    7241.25 mm squared
    note: π is pi
    Step-by-step explanation:
    The surface area of a cylinder is denoted by: A = 2πr² + 2πrh, where r is the radius and h is the height.
    We know that the diameter is 39.2 mm, and since diameter is twice the
    radius, then r = d/2 = 39.2/2 = 19.6 mm. We also know that the height is 39.2 mm, so plug these values in:
    mm, so plug these values in:
    A= 2 π r² + 2πrh
    A = 2π(19.6)² + 2π * 19.6 * 39.2
    = 7241.25 mm squared
    The answer is about 7241.25 mm squared.
    i think, sorry if this isn’t the right answer, have a good day/night!
