Answer:

A ray is known as a half-infinity line. As it starts from a point while the other end is pointing towards the direction till infinity.

As already discussed ray shows a direction as well, therefore, it is a vector quantity and is denoted by an arrow over the line name.

As shown below a ray can be drawn. therefore, which is starting from point A and continuing toward the right side infinity.

Step-by-step explanation:

The volume of a cone is 3x* cubic units and its height is x units.

igor_vitrenko [27]

Answer:

The radius of a cone is $\dfrac{3}{\sqrt{\pi} }\ \text{units}$ .

Step-by-step explanation:

The formula of the volume of a cone is given by :

$V=\dfrac{1}{3}\pi r^2 h$

r is radius of cone

h is height of cone

We have,

Volume of a cone is 3x cubic units and height is x units. Putting the values of volume and height such that,

$r=\sqrt{\dfrac{3V}{\pi h}}\\\\r=\sqrt{\dfrac{3\times 3x}{\pi x}} \\\\r=\sqrt{\dfrac{3\times 3}{\pi}}\\\\r=\sqrt{\dfrac{9}{\pi}}\\\\r=\dfrac{3}{\sqrt{\pi} }\ \text{units}$

So, the radius of a cone is $\dfrac{3}{\sqrt{\pi} }\ \text{units}$ .

Pls help with this volume wiestion

Zielflug [23.3K]

Answer:

15833.6269741 cm^3.But we can make it 15,833.63 cm^3 rounded to the nearest hundredth.

Step-by-step explanation:

so let’s solve this using the following formula -> $V=\pi r^2h$ .

So if the height is 25 and the radius is 12 them we can plug those numbers into the formula.

$\pi (12)^2(35)$ .

So let’s start by doing 12 squared which is 144 then 144*35 which is 5040.

And now 5040*pi which is 15833.6269741 cm^3.But we can make it 15,833.63 cm^3 rounded to the nearest hundredth.
