Question

What is the surface area formula for a cone?

Answer 1

Here is your answer,

S.A. of cone = πr (l+r)

l = slant height
r = radius



HOPE IT HELPS YOU !!!

Answer 2

Hey there !!

Question :-

→ What is the formula of the surface area of a cone ?

Answer :

There are two types of surface area in a cone :-

1 . Total surface area [ TSA ] .

2. Curved surface area [ CSA ] .

Now, formula :-

→ TSA of cone = πr( l + r ) .

→ CSA of cone = πrl .

Where, r = radius  ; l = slaint height .

Volume of a cone = 1/3πr²h .

Hence, it is solved .
