  1. I have no idea how to do this problem. You’re given the diameter of the blue sphere, NOT the actual globe. Are we supposed to look that up? Please enlighten me on how to get the answer.

    1. Hi Jeff,

      This problem is only meant to be an estimation challenge. I don’t want students to have the needed information because I want them to focus on making a guess instead of getting the correct answer. That’s why I gave the diameter of the blue circle. Students can use that diameter to estimate the dimensions of the sphere.

      Thanks for the comment!
