Question

What is lateral surface area of a right circular cone

Answer 1

Answer:

LSA of right circular cone = py r l

r= radius of base

l=slant height

= root(h² + r²)

h= height of cone

Step-by-step explanation:

Answer 2

Lateral surface area of a right circular cone is Π x R x l.

• All sides of an object, excluding its base and top, are considered its lateral surface (when they exist). The size of the lateral surface is referred to as its area.
• This must be distinguished from the total surface area, which consists of the base and top areas as well as the lateral surface area.
• The lateral surface area of right circular cone is πrl where r is radius of base of cone and l is the slant height of cone which is calculated using radius of cone and height of cone
• l = $\sqrt{r^{2} + h^{2} }$ where h is the height of cone and r is the radius of base.
