A conical hole is drilled in a circular cylinder of height 12cm and base radius 5cm. The height and base radius of the cone are also the same. Find the total surface area of the remaining solid
-------------------
The lateral area of the cylinder is 2pi*r*h
The area of one end is pi*r^2
The area of the cone is s*r*pi where s is the slant height.

Add those.
