Answer:
It is given volume of a cylinder =1650cm
πr
2
h=1650 ...(1)
It is given that curved surface area of cyliner =600cm
2πrh=660cm ...(2)
On solving (1) & (2)
2
r = 660
1650
r= 330
1650
r=5cm
Substitute r=5 in (2), we get
2πrh=660
2.

22×5×h=660
2×22×5×h=660×7
22×h=4620
h= 220
4620
h=21cm
∴ radius of cylinder =5cm
Height of the cylinder =21cm
sorry mate
sorry mate i don't know the total surface area
