Question 1170246
.
1.a) Deduce that the total surface area S of a cylinder closed at both ends with height, 
H and base radius R is given by: S=2πR(R+H) where π is a constant.
b) Find the volume of S given that H =15.0m and R =5.0m (leaving your answer in terms of π)
c) Calculate the amount of water the tank can hold leaving your answer in terms of π.
d) Calculate the height (h) of a cuboid tank of cross-sectional area 25 metre cube 
which has the same capacity as the cylinder tank in (c) above.

How your problem is printed and presented in this post - it is a  MESS,
impermissible in  Math.


Thus,  in part  b)  you write  " Find the volume of S ",  but letter S is just employed 
in part  a),  where it denotes the surface area.    You can not use it for the volume.


In part  d)  you write  " cross sectional area  25  metre cube", 
but cross sectional area is  NEVER  measured in meters cube:  the adequate measure unit is meter square.



        Writing  Math problem is not the same as celling vegetable and fruits 
        at the farmer's market.   It requires accurate using of words.



All calculations in the post by @mananth in parts  b),  c)  and  d)  are   {{{highlight(highlight(FATALLY))}}}   {{{highlight(highlight(wrong))}}}.


If you want to get accurate answer/solution,  you should print/present your post/problem accurately.



        Revise your post,  fix your errors,  then re-post.



Do you re-write your problems from a source (like textbook), 
or translate them from other language, or get them by phone, or create on your own ?



If you copy-paste it from some Internet site/file, then it means that this source is DEFECTIVE.



        In whole, the creator of this post deserves a ticket 
        and a penalty for his (or her) unsatisfactory job.
