Given a cylinderical tin with radius of each cross section 3m and hight 6m. Calculate it's Surface Area.
a. The two (2) ends are not closed.
Ans:: S = 2*pi*r*h = 2pi*3*6 = 36pi sq. meters
------------------------------------
b. One (1) end is closed.
Ans:: S + pi*3^2 = 36pi+ 9pi = 45pi sq meters
-------------------------------
c. The two (2) ends are closed.
Ans:: S + 2(pi)*9 = 45+9pi = 54pi sq meters
-------------
Cheers,
Stan H.
