Question

write the formula to find curved surface area of a cone and explain each term in it

Answer 1

CURVED SURFACE AREA OF CONE IS

A = πRL

HERE ,

R = RADIUS OF BASE OF CONE

L = SLANT HEIGHT OF CONE...

HOPE IT HELPS

Answer 2

Answer:

The curved surface area of cone is π$rl$.

Step-by-step explanation:

Curved surface area is also called as lateral surface area.

The curved surface is defined as a rounded surface which is not flat.

For the cone of radius $r$, height $h$ ands slant height $l$, the curved/lateral surface area is calculated as π$rl$.

There is a right angle between height and radius of base,

So slant height is calculated as

$l^{2} =r^{2}+h^{2}$

$l=\sqrt{r^{2}+h^{2} }$

Hence formula is π$rl$.

π is $22/7$

$r$ is radius of base

$h$ is height
