FRUSTRUM not frustration -- Boy, that is frustrating!
There is not enough information, because we don't know the height of the cylinder. Let's say that
the cylinder has height c
the frustrum has height h, and slant height s
Then all we know is that
4h+c = 12
s^2 = h^2 + 4^2
The figure represents a conical flask.The flask consists of a cylinder part and a frustrating of a cone.The diameter of the base is 10cm while that of the neck is 2cm.The vertical height of the flask is 12cm
Calculate the slant height of the frustration part
