Question

Need help with this geometry question asap!

Answer 1

`v = \pi \: {r}^(2) h \\ where \: v = 162\pi \: \\ r = 3 \\ h = \frac{v}{ {r}^(2) } \\ h = (162)/(9) \\ h = 18 units`

Answer 2

Height = 18 units

Explanation:

Given :

Volume= 162pi, radius= 3 units

We know,

Volume of Cylinder= Pi * (radius)^2*h

now you can substitute, (P.S: dont put the value of pi as it will get cancelled)

162 pi = pi* (3)^2* h

162= 9h

∴h= 162/9= 18

∴ height is 18 units.

Hope it helps. But I am not sure if the answer is correct or not.
