A tent consists of a cylinder surmounted by a cone. Which of the following does the total surface area of the tent not consist of?
One circuler section of cylinder, Base area of cone
The above diagram represents the tent. It can be considered as a combination of a cylinder and a cone.
The cone is placed on top of the cylinder. When this happens the top flat surface of cylinder and bottom flat surface of cone join together. These 2 surfaces will now be inside the combined solid and hence will be invisible to the eye.
In other words these 2 surfaces- one circular section for cylinder and circular section of cone will not be a part of the tent’s total surface area.
