Step-by-step explanation:
No. of glasses=(V. of jug)÷V. of cylinder
=1540/πr²h
=1540/(22/7×7/2×7/2×8)
=(1540×4)(/154×8)
=40÷8
=5 glasses

Answer:
The correct choice is (b) 5
Explanation:
Volume of a cylindrical glass = πr^2h
= 227 * 3.5 * 3.5 * 8
= 308cm^3
Volume of a water jug = 1540cm^3
Therefore, number of times the water has to be poured from glass to fill the jug completely
= Volume of a water jug/ Volume of a cylindrical glass = 1540/308
= 5.
