FAQs on 04 - Volume Of A Sphere - Class 10 - Maths Video Lecture

1. What is the formula to find the volume of a sphere?
Ans. The formula to find the volume of a sphere is V = (4/3)πr³, where V is the volume and r is the radius of the sphere.
2. How do you calculate the volume of a sphere if only the diameter is given?
Ans. To calculate the volume of a sphere if only the diameter is given, we first need to find the radius. The radius can be found by dividing the diameter by 2. Once we have the radius, we can use the formula V = (4/3)πr³ to calculate the volume.
3. Can the volume of a sphere be negative?
Ans. No, the volume of a sphere cannot be negative. Volume is a measure of space, and it cannot have a negative value. The volume of a sphere will always be a positive value or zero.
4. What is the unit of measurement for the volume of a sphere?
Ans. The unit of measurement for the volume of a sphere depends on the unit of measurement used for the radius. If the radius is measured in centimeters, then the volume will be measured in cubic centimeters (cm³). Similarly, if the radius is measured in meters, the volume will be measured in cubic meters (m³).
5. How is the volume of a sphere related to its surface area?
Ans. The volume of a sphere and its surface area are related, but they measure different aspects of the sphere. The volume represents the amount of space enclosed by the sphere, while the surface area represents the total area of the sphere's outer surface. However, there is no direct formula to calculate the surface area of a sphere using its volume.
