To find: What is the maximum volume of the cylinder?
The volume of cylinder as a function of h would be V=π4(256h−h3) . The value of h would be approximately 9.24 . The maximum volume of the cylinder is about 1238 cubic units.
Given information:
A cylinder is inscribed in a sphere of radius 8.
Formula used:
Volume of cylinder is πr2h , here r represents radius and h represents height of the cylinder.
Calculation:
First of all, find the radius of cylinder using Pythagoras theorem. Draw a right triangle as shown below:
Here D is diameter of the cylinder. Using Pythagoras theorem, the set-up would be:
D2=(8+8)2−h2D2=162−h2D2=256−h2D=√256−h2
It is known that radius is half the diameter, so radius of the cylinder would be r=√256−h22 .
V=πr2h=π(√256−h22)2h=πh(256−h24)=π4(256h−h3)
Therefore, the volume of cylinder as a function of h would be V=π4(256h−h3) .
Upon graphing the volume function, the required graph would look like as shown below:
It is visible that the maximum volume is about 1238 cubic units and occurs when x≈9.238 , therefore, the value of h that maximizes the volume would be 9.24 units.
