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