1- a metalic pipe is .7cm thick inner radius of the pipe is 3.5cm and length is 5dm find its total surface area
------------
The length is 50 cm
The inner radius is 3.5 cm
= 350pi sq cm
---------------
The outer radius is 4.2 cm
= 420pi sq cm
-----------------
The area of each end is sq cm
=====================
Total area = 780.78*pi sq cm
