Topics Covered in Exercise 11.1 Class 9 Mathematics Questions
In ex 11.1 class 9 maths solutions, students will learn how to find the surface area of a right circular cone in a simplified way.
1. 
Surface Area of a Right Circular Cone 

Surface Area of a Right Circular Cone
Right Circular Cone  The right circular cone is defined as a circular cone with an axis that is perpendicular to the base of the cone.
In NCERT Class 9 Maths Chapter 11 Ex 11.1, the formulas for cone are as follows:
Curved Surface Area of a Cone = (1/2) × (2πr) × l = πrl
where "r" is the base radius and "l" is the slant height.
l = √r2+h2
Total Surface Area of a Cone = Curved surface area(CSA) + area of base
= πrl + πr2 = πr(l + r)
