Hello !!
Circumference of base of cylinder = 120 cm
2πR = 120
2 × 22/7 × R = 120
R = ( 120 × 7 ) / 44
R = 19.09 cm
Curved surface area of cylinder = 4800
2πRh = 4800
2 × 22/7 × 19.09 × H = 4800
H = ( 4800 × 7 ) / ( 2 × 22 × 19.09)
H = 33600/ 839.96 = 40 cm
Therefore,
Volume of cylinder = πR²H
=> 22/7 × 19.09 × 19.09 × 40
=> 45813.818 cm³.
