Question

The radius of a cone is 5 cm and vertical height
ks 12 cm. Find the area of the curved surface​

Answer 1

Answer:

$204.29 \: {cm}^{2}$

Step-by-step explanation:

given, h = 12cm

r = 5cm

So, l(slant height)=

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

=13cm

And CSA of Cone = πrl

=π×5×13

=204.29 approx.
