A cone has a diameter of 8 cm. and a height of 4cm.   If the height doubles then the volume is: a) four times larger
b) three times as large
c) Twice as large
d) The same

the answer is c
its because volume of cone isπr²h
 given d=8cm i.e r= 4cm  h= 4cm
by applying the formulae 22/7×4×4×4=201
if the height is doubled the
h=8cm r = 4cm
again by applyng the same formulae
22/7×4×4×8=402
thus we can conclude that 
   if the height is doubled then the volume will be doubled
       i hope i helped u.

The answer is c.

As we know, volume of cone = 1/3 πr²h

As we can see from the equation, volume of cone is directly proportional to the height. Thus, as the height increases, volume also increases.
