Question

TUU SILICU.

Answer 1

Answer:

$r = 5 , V= 105$

And for this case we want to find the height, if we solve for h from equation (1) we got:

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

And replacing we got:

$h = \frac{3*105}{3.14 (5)^2} = 4.01$

And then height would be given by:

$h =4.01 units$

Step-by-step explanation:

For this case we know that the volume for a cone is given by this formula:

$V = \frac{\pi r^2 h}{3}$ (1)

And from the info given we have:

$r = 5 , V= 105$

And for this case we want to find the height, if we solve for h from equation (1) we got:

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

And replacing we got:

$h = \frac{3*105}{3.14 (5)^2} = 4.01$

And then height would be given by:

$h =4.01 units$

Answer 2

Answer:

4.013 units

Step-by-step explanation:

We know that the volume of a cone is given by the following equation:

v = pi / 3 * r ^ 2 * h

we need to know the height, therefore we solve for h:

h = 3 * v / (pi * r ^ 2)

replacing v = 105 and r = 5

h = 3 * 105 / (3.14 * 5 ^ 2)

h = 4.013

Which means that the height measures 4.013 units
