Finding the height of a clylindrical silo with just the volume

[kgbwolf]

The question is find the height of a cylindrical silo that has 1000m3. I have no idea what to do.

There must be some other dimension that you can get. diameter? circumference? Can you actually go to this silo?

 

[kgbwolf]

on the previous problem i worked out that the same silo has a Curcumfrence of 29.5m and a diameter of 9.39 m

OK, you need to write down two equations then put them side by side:

one is the equation for the circumference of a circle (in terms of its radius); the next is the equation for the volume of a cylinder (also in terms of its radius, and height).

If you knew the radius if a cylinder, and its volume, could you calculate its height?

I know volume is (PI)(r2)(height)
i think curcumference is (PI)(r2) divided by 2

The equation for circumference is (pi)d; where d is the diameter

The equation for circumference is (pi)d; where d is the diameter

Also known as C = 2 (pi) (r)
