Question

In a cone , its radius = 5 cm , height =12 cm
Find (A) Slant height =
(B) C.S.A =
(C) T .S .A =
(FIND VALUE IN TERMS OF Π) (NOT PUT VALUE OF Π) ​ plz step by step​

Answer 1

Answer:

The curved surface area of a cone is πrl, where r is the radius and l is slant height

We need to calculate slant height, it can be done by using the formula l

2

=r

+h

, where h is height.

So, l

=

r

2

+h

​

=13

We have curved surface area of a cone is πrl =π×5×13 =65π cm

2

Hence, the answer is 65π cm
