--description--

What is the length of the shortest pipe, of internal radius 50mm, that can fully contain 21 balls of radii 30mm, 31mm, ..., 50mm?

Give your answer in micrometres (10-6 m) rounded to the nearest integer.

--hints--

assert.strictEqual(euler222(), 1590933);

function euler222() {

  return true;
}

euler222();
