A right cylinder has a height of 1 cm and a radius of 1 cm . suppose each is tripled . how does the volume of the new cylinder compare to the original cylinder?

Question

anonymous · Answer

V = pi*(r)^2*h so when u triple the radius r^2 gets multiplied by factor 9 then u triple h so the volume is multiplied by factor 27

anonymous · Answer

After calculating, you will get the new volume= 27 the old volume
hope it helps

anonymous · Answer

so when i substitute the values it would be V= pi(3)^(7)

anonymous · Answer

@seran is correct
the first volume is pi cm^2 and the second is 27pi cm^3

anonymous · Answer

sorry, should say cm^3 above, typo
