Question 1011932
A cylinder is inscribed in a sphere of radius 1. Express the volume V of the cylinder as a function of the base radius r. (The final answer must not contain any variable other than r. Please show all steps including algebra clearly)
let base radius of cylinder is r
radius of sphere is 1 given 
height of cylinder  will be 2 unit 
volume of cylinder = pie r^2h= pie r^2x2 =2pie r^2
can be solved further  use pie=3.14 or 22/7
2x22xr^2/7=44r^2/7
or
2x3.14r^2=6.28r^2
