Let's do this question, a spirit of radius are as the same volume as that of a cone with a circular
base of radius to find the height of the cone.
All right.
Pause the video, give it a try, and then let's do it together.
All right.
We're back.
Let's do it together.
Now, the volume of a spear has given us four by three by our cube.
Right.
And the volume of a cone is given us one by three by our square inch.
But in this case, the radius is to our right.
So let's take it as two are.
Therefore, the volume of the cone will be one by three by Endou to our square.
It's right.
And over here it's given that these two are equal.
So let's equate them so you get four by three.
Bay'ah Cube is equal to one by three.
Bite into four square into X.
Right.
Now let's simplify it over here.
These three and this three gets canceled.
All right.
This four and this four gets canceled.
This by and this by gets canceled.
So you're left with our cube is equal to our square into each.
Right, or you get R is equal to it.
That is the height has to be equal to the radius and that is option C over here.
