I am having trouble with these two problems, I was wondering if anyone here could help me.(adsbygoogle = window.adsbygoogle || []).push({});

1. Given a sphere of radius 10 inches. Calculate the altitude of the inscribed right circular cylinder of maximum volume.

2. A man 6 feet tall walks away from a light 30 feet high at the rate of 3 miles per hour. How fast is the further end of his shadow moving, and how fast is his shadow lengthening?
