Answer:

Volume of remaining solid = volume of cylinder - volume of cone.

r=5 cm (given)

h=12 cm

Volume of cylinder = πr

Remaining volume = 942-314

=628cm

Total surface of remaining solid = conical sutface area of cone + Area of circle + Cylindrical area of cylinder.

Conical sutface area of cone =πr

Cylindrical area of cylinder = 2πrh

=376.8cm
