Answer:
Volume of the remaining solid Volume of the cylinder Volume of the cone
Slant height of the cone
Now, total surface area of the remaining solid
= Curved surface area of the cylinder +
area of the base of the cylinder + curve
surface area of the cone
= (2 x 6 x 8 + x 62 + x 6 x 10) cm2
= (96 + 36 + 60) cm2
= 192 192 x 3.1416
= 603.1872 = 603.19 cm3
