Question

type the correct answer in the box. The formula for the volume, V, of a cone having the radius, r, and the height, h, is shown below. Write the formula to calculate the height, h.

Answer 1

You have to make h the subject using volume of cone formula :

`v = (1)/(3) * \pi * {r}^(2) * h`

`3v = \pi {r}^(2) * h`

`\frac{3v}{\pi {r}^(2) } = h`

`h = \frac{3v}{\pi {r}^(2) }`
