Question

If the heights of the two cylinders are equal and their radii are in the ratio 7:5 then the ratio of their volumes is

Answer 1

HELLO DEAR,

Let the radii be 7r, 5r of two Cylinder.

Let the height be h and h.

Then, Using Formula of Volume

Volume = πr²h

thus, according to the question

Volume = πr²h /πr²h

Volume = π×(7r)² × (h) / π ×(5r)² × h

Volume. = 49r²× h/25r²× h

Volume = 49/25

Therefore, the ratio of their volume is 49:25

I HOPE IT'S HELP YOU DEAR,

THANKS

Answer 2

Answer:

Step-by-step explanation:Acco to our question..

h=h

Radius is r

It is in the ratio of 7:5

So 7r:5r or 7r/5r

Volume =πr²h

So in ratio

πR²h : πr²h or πR²h/πr²h

π get cut...so 7R²h/5r²h

49R²h/25r²h

Both r²h and R²h get cancelled in division

So it is in the ratio of 49/25 or 49:25
