A package of modeling clay was shaped like a cone with a radius of 24 cm and a height of 6 cm. Miriam used all the clay to make a cylinder with a radius of 16 cm.

What was the height of the cylinder?
Use 3.14 to approximate pi, and express your final answer in tenths.

____ cm
I think 3000 or 32555.52

how did you solve this?

jokersmart · Answer

I got the answers didn't I? :\ I can't really choose between the two, so all i really wanna know is which one is correct. If you can't do this I'll try asking someone who can
This math I'm working on isn't easy.

anonymous · Answer

Does it make sense that the height would be 3000 cm? look at the numbers used in the question

anonymous · Answer

I got an answer

jokersmart · Answer

I'll just go with 32555.52 then.

anonymous · Answer

lol, that's not my point. Doesn't 3000 cm seem way too big to be a reasonable answer

jokersmart · Answer

Other than that I guess 4.5? Doubt it though

anonymous · Answer

So what i did was find the total surface area of the cone

anonymous · Answer

$$\pi r(r+\sqrt{h ^{2}+r ^{2}})$$

anonymous · Answer

use that formula to find the surface area

anonymous · Answer

of the cone

anonymous · Answer

r is the radius: 24 cm. and h is the height: 6 cm

jokersmart · Answer

I just wanna know if I'm correct on my answers, if not just say so please.

anonymous · Answer

you're not right

jokersmart · Answer

Okay, thanks. I'm gonna go over on what I worked on
