The solid consists of a trapezoidal prism with a cylindrical hole of radius $10$cm in the centre.  

Given that $AB=25$cm, $EF=75$cm, $FG=28$cm, $CF=DE=93.41$cm and the height of the solid is $90$cm.

Calculate the total surface area of the solid.

The solid is melted and recast into a cylindrical solid of height $40$cm, find the radius
 of the solid.
