Question
A cylinder with height 2x is inscribed in a sphere with radius 10.
a. Show that the volume of the cylinder, V, is
2Tx(100 - x).
b. By using_calculus, one can show that V is maximum when
10V3
Substitute this value for x to find the maximum
3
volume V.
c. (Optional) Use a calculator or a computer to evaluate
V = 2nx(100 - x) for various values of x between 0 and
10. Show that the maximum volume V occurs when x = 5.77.
