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

Answer:

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

$v = \frac{1}{3} \times \pi \times {r}^{2} \times h$

$3v = \pi {r}^{2} \times h$

$\frac{3v}{\pi {r}^{2} } = h$

$h = \frac{3v}{\pi {r}^{2} }$
