Write True or False and justify your answer for the following:
A solid cylinder of radius r and height h is placed over other cylinder same height and radius . The total surface area of the shape so formed is `4pirh + 4 pir^(2)`.

Text Solution

AI Generated Solution

To determine whether the statement is true or false, we need to calculate the total surface area of the shape formed by placing one solid cylinder on top of another solid cylinder, both with the same radius \( r \) and height \( h \). ### Step-by-Step Solution: 1. **Understanding the Structure**: - We have two solid cylinders, each with radius \( r \) and height \( h \). - When one cylinder is placed on top of the other, they share the top base of the bottom cylinder and the bottom base of the top cylinder. ...
