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

2. 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 =... ?

4. hartnn

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

5. katlynnn

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

@hartnn

7. 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 =... ?

8. katlynnn

i got 6 this time @ hartnn

9. katlynnn

@hartnn

10. katlynnn

nvm itd 4

11. hartnn

no, no.... $$\large \dfrac{4}{\cancel 3}\times\cancel 3=4$$ yes! 4
