# NCERT Solutions Class 9 Maths Chapter 13 Exercise 13.8 Surface Areas and Volumes

The NCERT solutions for Class 9 maths Chapter 13 exercise 13.8 Surface Areas and Volumes explains the volume of a sphere. With the help of an experiment involving a trough, a container, a sphere, and water, the students will observe that the volume of the sphere is the same as the volume of the water displaced by it. We get the same conclusion by repeating this experiment with spheres of different radii, meaning that the volume of a sphere is equal to (4 / 3) π times the cube of its radius.
