Learn moreIn our day-to-day life, we come across a wide range of objects that are in the form of a combination of two or more solid shapes.
Let us discuss some real-life examples in this article.
1. Capsule
The capsule is a combination of two solids, cylinder and hemisphere.
Hence, to find the total surface area of the capsule is given by:
TSA of the capsule \(=\) CSA of the hemisphere \(+\) CSA of the cylinder \(+\) CSA of the hemisphere.
TSA of the capsule \(=\) \(2 \pi r^2 \) \(+\) \(2 \pi r h\) \(+\) \(2 \pi r^2 \)
\(=\) \(4 \pi r^2 \) \(+\) \(2 \pi r h\)
\(=\) \(2 \pi r (2r + h)\) square units
2. Circus tent
The circus tent is a combination of a cone and a cylinder.
3. Lollipop
The lollipop is a combination of a sphere and a cylinder.
