I) CSA= 2πrh
= 2 x 22/7 x 35/20 x 10
= 110m2

II) cost= 40/m2
= 40 x 110
= 4400 rupees]]> 2020-06-07 05:46:21 UTC https://padlet.com/lathajoy68/fh5ayoyxb9y/wish/614749317 Group 1 (answer) https://padlet.com/lathajoy68/fh5ayoyxb9y/wish/614749884 height = 14 
csa = 88cm
Radius = 4
diameter = 2
therefore CSA of this cylinder =2πrh
which is 88cm
