1.	From a solid circular cylinder with height 10 cm and radius of the base 6 cm, a circular cone of the same height and same base is removed. Find the volume of remaining solid and also find the whole surface area.
Answer» Given, r=6cm, h=10cm. Volume of remaining solid= `pir^2h - 1/3pir^2h`=`2/3pir^2h` =`2/322/76610=5280/7cm^3` Total Surface area=`2pirh+ pir^2+ pirsqrt(r^2+h^2)`=`22/7(2610+66+6sqrt(66+610))`=`22/7(156+ 12sqrt34)cm^2`
