just find the volume
22x20xh = π *1*1 *3.5
22*20*h =( 22/7)*3.5
20*h =.5
h = .5/20 =5/2 = 2.5 cm

nitirocks12pehtmu: ok sir

bharat9291: see it will be like 0.5 - 19.5

bharat9291: so for more than 0.5 and less than 19.5 right ?

bharat9291: yes sorry ,you are right ,it should become -0.5

bharat9291: plz check in NCERT in tell me question number

nitirocks12pehtmu: ok sir

nitirocks12pehtmu: pg 287 q4, its the same type but i used different values, because i wanted to know, what would happen if the lower limit is 0

bharat9291: the lower limit can't be zero here

bharat9291: your concern is right ,the values can't be negative

nitirocks12pehtmu: ok sir thank you
