Question

If the height and radius of a cone is tripled, then find ratio of volume of new cone and that of original.​

Answer 1

Answer:

New volume : Original Volume=27:1

Step-by-step explanation:

volume of cone= ⅓πr²h=v

if R=3r, H=3h

volume V= ⅓πR²H

V=⅓π(3r)²(3h)

V=⅓πr²h(3².3)

V=v(27)

V/v=27

V:v=27:1

new volume : original volume =27:1
