Explanation:
Let volume be v then:
Given: radius is r
Let length of cylinder be L
Volume of two ends when put together form a sphere
Volume of cylinder is circle area times length of cylinder
But
Both r and L are both measured in feet. so you can add the volumes directly, giving:
Putting the two together: ( 1 ) + ( 2 )
Let feet be ft
