Question

In a cone, radius is doubled and height is halved, find curved surface area of the new cone.

Answer 1

HEY MATE HERE IS YOUR ANSWER

C. S. A OF CONE = PIE rl
RADIUS = 2r
HEIGHT = H/2
SLANT HIEGHT =
${h}^{2} \sqrt{ {r}^{2} { + h}^{2} }$
4r+h/4
Slant height =1
C.s.a = 22/7 * 2r *1
=44/7 r

Answer 2

Answer:

RADIUS = 2r

HEIGHT = H/2

SLANT HIEGHT =

{h}^{2} \sqrt{ {r}^{2} { + h}^{2} }h

2

r

2

+h

2

4r+h/4

Slant height =1

C.s.a = 22/7 * 2r *1

=44/7 r
