From a cylindrical object of diameter 70cm and height 84cm , a right solid cone having its base as one of the circular ends of the cylinder and height 84cm is removed.
Calculate :
A) the volume of the remaning solid object , expressing your answer in the form a X 10n (10 raised to power n) where 1 Vol of the cylinder =
Vol of the cone =
---------------------
B) the surface area of the remaining solid object
The area of one end is
The lateral area =
The inner surface = the lateral area of the cone
Slant height = cm
Area = pi*r*SH
