# The volume of a cylinder of height 8 cm is 1232 cm^{3}. Find its curved surface area and the total surface area.

Answer :

It is given in the question that,

Height of the cylinder = 8cm

And,

Volume of the cylinder =

Hence,

We can find the radius as,

r =

r =

r = √49

r = 7 cm

Now,

Curved surface area of the cylinder =

=

= 252 cm^{2}

Therefore,

The total surface area of the cylinder =

=

= 2× 22× 15

= 660 cm^{2}
