Exercise 13.4 of 10th standard Maths have problems based on the topic- Frustum of a cone, which is a very important topic. Let us discuss here the formulas related to this topic;

• Volume of the frustum of the cone = ⅓ π h (r12+r22+r1r2)
• Curved surface area of the frustum of the cone = π(r1 + r2)l

where l = √h2+(r1 – r2)2

• Total surface area of the frustum of the cone = πl (r1 + r2 ) + πr12 + πr22,

where l = √h2+(r1 – r2)2

Based on these formulas given above, you will be solving questions in this exercise. Learn complete solutions for chapter 13 of class 10 maths from here.
