circumference of the base of the cylinder = 2πr
110cm. = 2×22/7×r
110×7/2×22=r
r = 17.5cm
curved surface area of cylinder = 2πrh
4400cm² = 2×22/7×17.5×h
4400×7/2×22×17.5= h
h = 40 cm
110cm. = 2×22/7×r
110×7/2×22=r
r = 17.5cm
curved surface area of cylinder = 2πrh
4400cm² = 2×22/7×17.5×h
4400×7/2×22×17.5= h
h = 40 cm
