Question

If a cylinder has the dimensions 4 cm as the height, and 2 cm as the radius, what the dimensions of the new cylinder be if the scale factor is 3:1?

Answer 1

we use a formula

Answer 2

oh, its just a proportion

Answer 3

Yes, what is the formula?

Answer 4

(4x / 2x) = 3/ 1

Answer 5

i think

Answer 6

ok thanks!

Answer 7

wait that dont make sense

Answer 8

hannnnnnnnahhhhhhh!!!!! you have a new picture

Answer 9

so pretty

Answer 10

i not sure about the order here

Answer 11

ignore what i said before. theres a diferent want to do this

Answer 12

ok

Answer 13

New linear measurement = Old linear measurement * scale factor

Answer 14

ok ?

Answer 15

So then would the dimensions of the original cylinder be multiplied by the scale factor? I think?

Answer 16

so we have 4 as an old linear measurement. so to find the new linear measurement
NL = 4 * ( 3/1) , where NL is new linear measurement

Answer 17

Oh ok! Thanks!

Answer 18

so the answer is 12 , and the other one is 6

Answer 19

is that the answer in the book

Answer 20

Yeah, should be thanks
