A rectangular container that measures 2 cm x 11 cm x 20 cm is completely filled with water. The water is then poured into a holl ow cylindrical container of base radius 5 cm. What is the height of water in the cylindrical container? A. 28/5 cm B. 14 cm c. 184/5 cm D. 88 cm
2 answers:
Answer:The volume of a rectangular container is
V = L X B X H, while the volume of the Cylindrical container is
V = pie( r^2)h where ( pie = 3.142 )
Volume of the rectangle = 2 x 11 x 20
= 440cm^3
Now to find the height of the cylinder we now equate the volume of the rectangle with that of the cylinder and make h the subject of the formula
440 = pie(r^2)h
= 3.142 x 5^2 x h
= 3.142 x 25 X h
=78.55h
440 = 78.55h
h. = 440/78.55
= 5.6cm
Step-by-step explanation:
Answer:
14cm
Step-by-step explanation:
formula of a rectangular container is LBH and we were given that LBH is 2*11*20 which is equal to 440cm.
Now when the water is transferred into a hollow cylindrical container.the formula for that is 2pierh.440=2*22/7*5*h
440*7=220h
3080=220h
h=14cm

Hello there!
Start by seeing if there is an equal rate in the qmount of people that we are working with.
27/9=3 (so there's one)
3*45 (the amount of time when 9 people are in line)= 135 minutes
Have a great day!
