Question

If height of a cone is doubled then its volume will increase by what peecent

Answer 1

1/3pie r^2×h
height is double
1/3pie r^2×2h
now.
increase in value
------------------------- × 100
original value
put this then
your answers will be came

Answer 2

SOLUTION

Let the original height = h

Then, volume = 1/3 π r² h

New height = 2h

So, volume = 1/3 π r² x 92hb)

= 2(1/3 π r² h)

Increase = ((1/3 π r² h)/(1/3 π r² h) x 100


= 100%
