# NCERT Solutions for Class 9 Maths Chapter 11 Exercise 11.3 Surface Areas and Volumes - PDF Download

NCERT solution for class 9 math chapter 11 ex 11.3 Surface Area and Volume uses examples to figure out how the volume of the right circular cone is one third the volume of the cylinder. There are two kinds of cones in math: the right circular cone and the oblique cone. Right circular cone is a type of cone that has an axis that's perpendicular to the base. You can see this in maths ex 11.3 class 9. The space or the capacity of the cone is referred to as the volume of the cone.

Class 9 maths chapter 11 exercise 11.3 NCERT solutions is composed of 9 questions. All the questions of ex 11.3 are based on finding the volume of the right circular cone.  Ex 11.3 class 9 maths solutions are carefully designed by our subject matter experts and teaching faculty at eSaral, which help students to perform well in examinations.
