Volume of cylinder = area of the base * height , or
V = pi*(r^2)*h
V,original = pi*(3^2)(10)
*you solve for this.
then for the new one,
r,new = 3*3 = 9
h,new = 3*10 = 30
V, new = pi*(9^2)(30)
you solve also for this.
then compare their volumes, find:
(V,new)/V
so there,, hope this helps~ :)
Thank you
is the answer 27?
yes,, (V,new)/V = 27,,
and ration of dimensions is 3 (because it is tripled according to problem)
now, how is 27 related to 3?
Y=5x;(15, -3)
