Step-by-step explanation:
The external diameter of a cylindrical shaped iron pipe is 25 cm and its length is 20 cm. If the thickness of the pipe is 1cm, find the total surface area of the pipe.
Surface Area of Pipe:
The external radius, internal radius, and thickness of the pipe can be used to find the pipe's surface area. If the external radius of the pipe is
R
, the internal radius is
r
,
and the length of the pipe is
h
,
then the surface area of the pipe is,
A
=
