Two cylindrical cans has the base of the same size. The diameter of each is 14 cm. The height of one can is 10 cm and another 20 cm. Find the ratio of their volumes.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 1 : 2
| Understanding | Application |
|
Diameter/2 = Radius Volume of cylinder = πr2h |
Volume of can 1st = π×72×10 = 490π Volume of can 2nd = π×72×20 = 980π Ratio = 490π : 980π = 1 : 2 |
