Question

21560 cubic cm of a liquid is filled in some cylindrical shaped containers of radius 7 cm and height 14 cm. Find the number of such containers required.

• A. 15
• B. 7
• C. 10
• D. 5

Answer 1

The correct option is C 10

Volume of entire 21560 cc of liquid will be equal to sum of volumes of cylindrical shaped containers. Hence,
Required number of such containers$=\frac{volumeofliquid}{volumeofthecontainer}=\frac{21560}{\pi \times r^2\times h}=\frac{21560}{\pi \times 7^2\times 14}=\frac{21560\times 7}{22\times 7\times 7\times 14}=10$
