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

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 =... ?

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

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 =... ?
