Write True or False and justify your answer:
Two identical solid hemispheres of equal base radius `r` `cm` are stuck together along their bases. The total surface area of the combination is `6pir^(2)`.

Text Solution

AI Generated Solution

To determine whether the statement is true or false, we need to calculate the total surface area of two identical solid hemispheres stuck together along their bases. ### Step-by-Step Solution: 1. **Understanding the Shape**: When two identical solid hemispheres are stuck together along their bases, they form a complete sphere. The bases of the hemispheres are joined, so they do not contribute to the external surface area. 2. **Formula for Curved Surface Area of a Hemisphere**: The formula for the curved surface area (CSA) of a single hemisphere is given by: \[ ...
