FAQs on Volume of a Cone Video Lecture - Class 9
| 1. What is the formula to calculate the volume of a cone? |  |
Ans. The formula to calculate the volume of a cone is V = (1/3)πr²h, where V represents the volume, r represents the radius of the base, and h represents the height of the cone.
| 2. How do you find the radius of a cone when only the volume and height are given? | |
Ans. If the volume and height of a cone are given, and you need to find the radius, you can rearrange the volume formula as follows: r = √((3V)/(πh)). Substitute the given values for V and h to find the radius.
| 3. Can the volume of a cone be negative? | |
Ans. No, the volume of a cone cannot be negative. Volume is a physical quantity that represents a measure of space, and it is always a positive value. Negative volumes do not have any physical meaning.
| 4. How can I find the height of a cone if the volume and radius are known? | |
Ans. To find the height of a cone when the volume and radius are known, rearrange the volume formula as follows: h = (3V) / (πr²). Substitute the given values for V and r to find the height.
| 5. Is the volume of a cone affected if the cone is slanted or tilted? | |
Ans. No, the volume of a cone is not affected by its slant or tilt. The volume of a cone only depends on the radius of the base and the height, regardless of its orientation in space. As long as the radius and height remain the same, the volume will not change.
