Question 3
A school provides milk to students daily in cylindrical glasses of diameter 7cm. If glass is filled
with milk up to a height of 12cm. Find how many liters of milk is needed to serve 1600 students.​

Answer 1

Answer:

739.2 liter

Step-by-step explanation:

diameter of cylindrical glass = 7 c.m

radius = 7÷2 =7\2 or 3.5c.m

height = 12c.m

volume of cylinder = π×r^2×h

22\7×3.5 ×3.5×12

462c.m ^3

I liter 1000 cubic centimeter

so 462÷1000= 0.462 litre

liter of milk needed to serve 1600 students = 0.462×1600

=739.2 liter
