The cylinderical cans have equal base area.If one of the can is 15cm high and other is 20cm high find the ratio of the Volume.​

Answer»

Answer:

3:4

Step-by-step explanation:

Given

  • Height of FIRST cylinder = 15

  • Height of second cylinder = 20

To find

  • Ratio of there area

\sf \boxed{ \sf \: volume \: of \: cylinder = \pi {r}^{2} h}

\sf \: volume \: of \: first \: cylinder = \pi {r}^{2} 15

\sf volume \: of \: second \: cylinder = \pi {r}^{2} 20

As we KNOW that area and base are same , we need not do any kinda further calculations by plugging extra number.

Now , arranging the obtained value in ratio form :

\implies \huge \frac{ {\cancel{\pi {{r}^{2}}}}15 }{ \cancel{\pi {r}^{2} }20}

\sf \implies \: \frac{15}{20} = \frac{3}{4}

Ratio = 3:4

What you need to know ?

  • Volume : 3-dimensional SPACE enclosed by a boundary or occupied by an object.

  • Ratio is COMPARISON between two known sets of values.
