Question

Keeping the radius
of
the base of a cone fixed,
if the height is
doubled, then how much
the volume of cone will increase ?
​

Answer 1

Answer:

2 times

Step-by-step explanation:

Volume of a cone,V=1/3πr^2h

where r=radius of the cone

h=height of the cone

If the height of the cone is doubled,

V'=1/3πr^2×2h

V'=2[1/3πr^2h]

V'=2V
