Assertion: A cone is a solid figure.
Reason: A cone is generated when a rectangular sheet is rotated about its axis.
Explanation:
A cone is indeed a solid figure with a circular base and a pointed top called the apex. It has a curved surface that tapers from the base to the apex. The reason given, stating that a cone is generated when a rectangular sheet is rotated about its axis, is not entirely correct.
When a rectangular sheet is rotated about one of its shorter sides, it creates a shape called a frustum of a cone, which is a cone with its top cut off. However, a cone itself is formed by rotating a right-angled triangle about one of its shorter sides.
To better understand this, let's consider the process of forming a cone:
- Take a right-angled triangle, where one of the sides is the height of the cone and the other side is the radius of the base.
- Hold the triangle by the right angle and rotate it about that side.
The rotation of the triangle creates a three-dimensional shape with a circular base and a curved surface that tapers to a point. This shape is a cone.
So, the assertion that a cone is a solid figure is correct. However, the reason provided to explain this assertion is not accurate. The reason wrongly states that a cone is generated by rotating a rectangular sheet, when in fact, a cone is formed by rotating a right-angled triangle.
Hence, the correct answer is option C: Assertion is true, but the reason is false.
