Question

If the volume of a cone is approximately 64 and the radius is 3.2, what is the approximate height? Use π=3.14.

Answer 1

h ≈ 6

Explanation:

Using the formula:

`V = (1)/(3) \pi r^(2) h` Or:
`V = \pi r^(2) (h)/(3)`

We can rearrange to make h the formula:

`h = 3 (V)/(\pi r^(2) )`

h= 3 (64/3.14×3.2²)

h = 3(64/3.14×10.24)

h=3(64/32.1536)

h=3(1.99044585987)

h= 5.97133757962

h ≈ 6
