The volume of a cylinder of height 8 cm is 1232 cm3. Find its curved surface area and the total surface area.
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 cm2
Therefore,
The total surface area of the cylinder = 
= 
= 2× 22× 15
= 660 cm2
