Volume of the cylinder=pi r^2 h
154=22/7*r^2*4
154*7/22*4=r^2
7/2=r
r=7/2cm
so LSA=2 pi*r*h
=2*22/7*7/2*4
=88cm^2
and TSA =2 pi*r*h+2 pi*r^2
=88+2*22/7*7/2*7/2
=88+77
=165cm^2

Hope it helps u...
srdeja123:
how did you get radius 7/2
154*7/22*4=r^2
so after cancelling u got 49/4=r^2
and now if u do the under root then u got 7/2 as the square of 49 is 7 and of 2 is 4
