From a solid cylinder whose height is \(2.4 \ cm\) and diameter \(2 \ cm\), a conical cavity of the same height and base is hollowed out. Derive the total surface area of the remaining solid.
Answer:
Slant height of the cone \(=\) \(cm\)
The total surface area of the remaining solid \(=\) \(+\) \(+\) Area of the base
The total surface area of the remaining solid \(=\) \(cm^2\)
