Question

25) An electric geyser is cylindrical in shape, having outer diameter of 74cm and
height 1.4m. If the thickness of its wall is 2cm, calculate
i) its volume ii) capacity.​

Answer 1

Answer:

Step-by-step explanation:

r = 37 cm h = 140 cm thickness= 2 cm

R = 39cm

i) Volume = π(R-r)(R+r)h

22/7 ( 39-37)(39+37) 140

22 * 20 * 2 * 76

66880 cm cube

ii) Capacity

Since 1000cm cube = 1 L

Capacity = 66880 / 1000

66.8 Liter
