We know that volume of the cylinder = πr2h
Here r = 14dm h = 15cm
V = 22/7 × 1.4 × 1.4 × 15
V = 92.4 cm3
Also we know that curved surface area of cylinder = 2πrh
Curved surface area = 2 × 22/7 × 1.4 × 15
Curved surface area = 132 cm2
We know that total surface area of cylinder = 2πr(r + h)
Total surface area = 2 × 22/7 × 1.4 (1.4 + 15)
Total surface area = 144.32 cm2
