the ratio of curved surface area to the total surface area of right circular cylinder is 1:3. Find the volume of the cylinder if its total surface area is 1848cm2. [ pie =22/7 ]

Hi!
Here is the answer to your question.
 
Let the radius and height of the right circular cylinder be r cm and h cm respectively.
Curved surface area = 2πrh
Total surface area = 2πr (r + h)

Given  - CSA  of cylinder : TSA of Cylinder :: 1 : 3

Let the CSA of cylinder be x

=     x

3  1848

 

x= 1848

  3

 

x = 616 cm2 

 

CSA of cylinder is 616 cm2
