R=30cm
V of hemisphere =2/3pie *r^3
=2/3*22/7*30*30*30=188.57
R of cylinder =30
H=1.45
V=22/7*30*30*1.45=4101.42

Step-by-step explanation:
Method : 4 ( Cube of any number).
Step 1 : Split the number as like i.e 7 – 28 or 72 – 8. ...
Step 3 : Cube of 1st part c = 8 x 8 x 8 = 512. ...
Step 4 : 3 bc + 51= (3 x 9 x 512) +51= 13824 + 51 = 13875 . ...
Step 5 : 3 b² c +13875= (3 x 9 x 9 x 512) +1387= 124416 + 1387 = 125803 .
