volume of cylinder=pi×radius^2×height
convert height into cm
then put values which are given
u can put pi = 22/7 or 3.14

Hey mate! here is your answer.
Height of circular cylinder = 1 DM = 10 cm
Volume of cylinder = 385 cm^3
pi ×r^2×h = 385^3
22/7×r^2×10=385cm ^3
r^2 = 385×7/2×22
r^2= 539/44
r = under root 12.25
r= 3.5
So radius = 3.5 cm then diameter = 3.5×2 =7cm
Hope it helps
