vol = 216 times

k= cube root [ 216]
k = 6

k = r/3
6 x 3 = r
r = 18

same way for height .. h = 6 x 7 = 42

remember always .. for vol k is k3 and area k2

(ratio of sides)3 = ratio of volumes
ratio of volumes is 1:216
so ratio of sides should be cube root of 1:216
ratio of sides= 1:6
to get lengths, multiply by 6
r=3x6=18cm
h=7x6=42cm
hope that helps!
(sorry VIN, didn't realise you answered already)

any ways  tk the invariant line as x=-1. the corner (-4,3) moves 4 spaces to the right along the invariant line and it is 3 spaces above the line.

i think this is correct bcause  we had gotten a similar question in our schl exams and the teacher had told us this
