Question

The radii of two cylinders are in the ratio 2:3 and their heights are in the ratio 5:3. Calculate the ratio of their volume ​

Answer 1

Answer:

volume =  Pi*r²*h

v1:v2 = r1²*h : r2²*h

= 2²*5 : 3²* 3

20 : 27

Step-by-step explanation:

Answer 2

Step-by-step explanation:

here is ur answer ..

let the radius of first be 2r

radius of secomd will be 3r

height of first be = 5h

height of second be = 3h...

now ratio of volumes =

$\frac{\pi {r}^{2} h}{\pi {r}^{2}h }$

$\frac{ {(2r)}^{2} 5h}{ {(3r)}^{2} 3h}$

$\frac{4 \times 5 {r}^{2}h }{9 \times 3 {r}^{2}h }$

$\frac{20}{27}$

so the answrr is 20:27
