Answer :-
We know that ,
Sum of height and radius of cylinder = 37m
i.e, (h + r = 37m)
Total surface area = 1628m
Formula of TSA of cylinder = 2πr (r+h)
TSA of cylinder = 2πr (37) = 1628m
2πr = 44m
πr = 22m
r = 7m
So, (r + h) = 37m
h = (37 - 7) = 30m

Total length of the cylinder (h + r ) = 37m
Total surface area of the cylinder = 1628 m
Formula to find the TSA of cylinder = 2π r( r+ h)
TSA = 2πr (37)
1628 = 2πr (37)
= 2πr
2πr = 44
πr =
πr = 22
r =
r = 7m
We already know that (r + h) = 37m
(7+h) = 37m
h = (37 - 7)
h = 30m
Volume of cylinder = h
= 30
=
= 462 {m}^{2}
So the volume of the cylinder is 462
