please help

Select one: a. h = 12 and r = 4 b. h = 6.75 and r = 4.5 c. h = 6.75 and r = 2.25 d. h = 12 and r = 8

hartnn (hartnn):

you just need to scale things by the given factor. \(new = k \times old\) here, k=4/3 old height =9 new hight = 4/3 * 9 =... ?

OpenStudy (anonymous):

so whats the answer? @hartnn

hartnn (hartnn):

you just need answers ?? also, the answer is in front of you! just do, (4/3)*9 for height

OpenStudy (anonymous):

i got 12 as the height but how do i find the radius?

@hartnn

hartnn (hartnn):

good! h=12 is correct do same thing for radius old radius = old diameter /2 = 6/2 = 3 new radius = k* old radius = (4/3)*3 =... ?

OpenStudy (anonymous):

i got 6 this time @ hartnn

OpenStudy (anonymous):

@hartnn

OpenStudy (anonymous):

hartnn (hartnn):
